Twenty Five Intel CPU Coolers Tested

Kez writes "Over recent years coolers have grown increasingly exotic in design, striving for good cooling performance and low noise even with the most power hungry of CPUs. But sometimes that comes at a price, be it straining the motherboard's socket to its limit, or the wallets of PC enthusiasts. Investigating which coolers do their job well without snapping your motherboard in two, HEXUS.net reviews 25 LGA775 coolers."

Aftermarket coolers are useless for most users.

[Spazntwich]

When was the last time a CPU failed at stock speed with the stock cooler?

The obsession with aftermarket cooling solutions for all but the harder core overclockers strikes me as about as ridiculous as engine oil companies' claims of their oil increasing engine life over other oils. When was the last time you heard about an engine seizing that didn't straight-up run out of oil or suffer from a factory error?

Re:

[mulvane]

Reduced power usage caused by cooler chips, not to mention thermal degradation over time (some people keep computers for a long time withtout upgrade) could be a factor..

Re:

[427_ci_505]

I'm pretty sure they're using the same amount of power, but just getting rid of wasted heat better. I might be wrong. Does a cooler chip need less power to do a certain action than the same chip running warm?

Re:

[Spazntwich]

Even if it does, the swing can't be more than a few watts in either direction.

Otherwise, Intel and AMD would release power usage under load numbers for various temperatures, and people constructing server centers would take that into account with their air conditioning decisions.

Aftermarket cooling's (non)impact on E consumption

[CaptKirk3]

No, the cooler is dissipating previously evolved heat generated by the amount of electricity moving through the processor. It's just wasted E left over from processing. To reduce the amount of power consumed by the processor, one must manually (or automatically in some cases) reduce the voltages associated with the operation of the CPU (Vcore) or throttle the clocks on the CPU. You can do some low V overclocking with very good cooling. You should also be able to run your voltages at lower temps even at sto

Re:Aftermarket cooling's (non)impact on E consumpt

[jacksonj04]

My physics says that resistance increases with heat, thus at higher temperatures you need a higher current to achieve the same voltage. Lower temp = lower resistance = lower current.

Re:

[mulvane]

Line resistance increases as heat rises. Its common electrical theory. That's one reason its good to use a large gauge wire and fuse it properly at the panel to decrease line loss over long runs with high power demands.

Re:

[Netsplitter]

A lot more people are aiming to have silent computers nowadays. While the cooling capabilities may suffice, they are very loud. Personally, I can't understand how anyone can be in the same room with the sound of a stock cooler, let alone try to sleep in the same room with one.

Re:

[Spazntwich]

Do you have any numbers for decibel ratings on more recent stock coolers and some aftermarket ones? I haven't been in the overclocking scene for a few years, but back then stock coolers were among the quietest available, short of going with the huge Zalman's.

Re:

[Netsplitter]

Actually I'll take back what I said. I just fetched my Code 2 Duo's stock cooler and plugged it in. It's actually fairly quite, although still somewhat audible since it's using an 80mm fan (or around that). Now, about those "back then" stock coolers. They were NOT quite. That's where my prejudice against them came from. I'm talking as late back as the Northwood Pentium 4's, since I never bothered with another one since.

Re:

Personally, I can't understand how anyone can be in the same room with the sound of a stock cooler, let alone try to sleep in the same room with one.

Speak for yourself. I actually can't sleep with my PC turned off. I'm so used to the noise of the fans, that if exposed to complete silence I immediately get paranoias that someone's coming to get me and someone's watching me.

But that nothing compared to the noise in my ears I hear without fan noise, from all the long ears of exposure to loud music.

I agree that some people make an obsession out of squeezing the most OCing or cooling out of their computers. Normal people like me, however, like to have a silent computer and you just can't compare something like a Zalman to a stock cooler, noisewise. Besides, it looks good in my windowed case at LAN parties :)

Re:

[PhoenixFlare]

Maybe I just had a slightly defective unit or something, but the stock cooler on my Intel CPU (Celeron D 351 3.20GHz) would routinely idle around 50 C or so, and hit 70 degrees C or higher under load, even running an ancient game like Starcraft - my fans would rev up high enough to sound like jet engines.

In contrast, I swapped it out with one of the reviewed coolers (the Arctic 7 Freezer Pro), and I see at least a 10 degree difference (or more) in pretty much everything i've run since then.

Re:

[PhoenixFlare]

Yeah, no doubt that was part of the problem - I have 2 long-haired cats that enjoy hanging out around the computer, and they definately contributed some fur (though I did clean it out as best I could, and it did help a little, to be fair), but not enough to where I really felt safe with the temperature readings if I did anything but websurfing.

I think it ran me about $30 + shipping for the new cooler, if memory serves, so it was easier than trying to futz around with the old one.

Re:Aftermarket coolers are useless for most users.

[ben there...]

If you look at the prices for Core 2 Duos [newegg.com], the difference between something like the E6600 and the X6800 is $750. Slap a $50 cooler on the E6600, clock it up to 3.2 GHz easily (~3.6 GHz max on air) and you have a CPU that performs better than one that would have cost you $700 more. You'd have to be kinda crazy not to overclock the Core 2 Duos.

You're right that most users don't, but they should. It's a worthy investment.

Re:

[drsquare]

Overclocking isn't exactly easy. When I try to overclock my core 2 duo it just doesn't start up. It's not something anyone can do.

Overclocking difficulty

[CaptKirk3]

Anyone CAN do it, provided they attain a certain level of knowledge about A. How the hardware functions to do it's job, and B. How to INCRIMENTALLY increase the performance of the system (by tweaking of individual component parameters to affect the whole). Most of the secrets can be found in wonderfully written how-to's on enthusiast websites.

It's not easy, but it's not very hard either. Rather it's time consuming, but as a previous poster mentioned it also delivers very tangible rewards much like a "70%

Re:

[snuf23]

It was extremely easy on my Core 2 Duo 6600. Of course I have an Asus board that has proper settings for easy overclocking. All I needed to do was boost the FSB to get to 3.0GHz, 100% stable on stock air cooling. But then maybe I got lucky with my chip.

What kind of motherboard do you have?

[Rob Simpson]

Some boards, such as my Asus P5W DH Deluxe have different ways to overclock, some of which are absurdly simple, such as "overclock 30%". By looking at the values it used, and a quick google search, it didn't take me long to figure out how to overclock to much faster speeds with the manual settings. (The problem I had at first was setting my memory far too fast and making the system crash. By setting it to ~800 mhz, I got my processor stable at 3.5GHz easily.)

Re:

[drsquare]

I've figured it out now anyway, got it from 2.13 to 3.2.

Try Easytune5

[edxwelch]

There's this application that comes with gigabyte motherboards specially for newbies (like me), it's called Easytune5. When you open it, it has two big buttons, up and down. Clicking up increases clockspeed in 1% increments. I upped the clock speed on my E6600 by 15% using this method and everything works fine. I could hear no fan noise increase and I am using stock cooler.
Of coarse, you could tweak a lot more performance out of it, if you want to go mucking around with bios settings, but I just don't have

In the last three years, the machine under my desk at work has had its CPU replaced once, and motherboard replaced four times due to fan failures.

Oil Breakdown.

[LibertineR]

Its a real thing.

Under certain conditions, the motor oil in your car can literally cook itself into a solid, and stop lubricating an engine.

If you are lucky, your radiator overheats before you blow a gasket separating oil from water. Get water into a place where oil goes and all kinds of things can go wrong.

The answer? Synthetic oil only. It does prolong engine life, especially in older cars with lots of miles on them. No matter how hot they get, they dont cook off and stop lubricating an engine. Also

The Zalman CNPS series is nice

[bcmm]

I have a CNPS7700-AlCu. It's a cheaper one than the one they review - and also smaller. The piece of metal with the vanes sits straight on the CPU with no heat pipes or anything. What they don't mention is that even my smaller cooler is technically out-of-spec - they're heavier than a LGA775 cooler should be, but motherboards don't actually snap that easily.

Anyway, the cooler comes with a device for adjusting it's speed, and it is practically silent on the lowest setting while still providing pretty good cooling. It helps that my processor isn't a very hot one (Intel Core 2 Duo 6300), but even on the silent setting I cannot make it go over 49 C. In fact, the vanes have enough surface area that if it's a cold day, the cooler works fine disconnected, i.e. without the fan turning.

As they say, fitting it can be a pain, but that is presumably the price you pay for fitting some 700g of copper on the motherboard.

By the way, it's worth taking measurements or checking their list of supported motherboards - it's physical dimensions are beyond the LGA775 spec as well. It extends out over the components immediately surrounding the CPU, and on my motherboard it neatly blows air through the northbridge and GPU heatsinks.

Re:

[ben there...]

Link to the 7700-AlCu [newegg.com] you mentioned.

I have the 9700 NT [newegg.com]. Like you, I was concerned with the huge size and weight of some of the towers. The Zalmans provide most of the benefit of the towers (performance, "silent"), while weighing in much closer to spec. They also include the fan, rather than some of the towers where you attach a 120 mm. That can be good or bad depending on whether you wanted to install your own quiet fan.

The difference between the 9700 LED that they reviewed and the 9700 NT that I own is pri

Re:

[bcmm]

The 7700 has a somewhat strange way of controlling fan speed. Irritatingly, it cannot be controlled through software like some fans, but instead has a little box with a variable resistor adjustable by a little knob, with an adhesive patch to mount it outside the case. Maybe it's because it's harder to silence a pulse width modulated fan than one which is regulated by a constant voltage.

Something weird with their testing methodology

[A Friendly Troll]

Some really, really great coolers, like the Noctua U12 or the Ultra 120 Extreme, don't fare very well on their test.

Also, if you haven't noticed, there's no word about fan noise... Which is extremely important to a lot of people. What good is a couple of degrees difference between cooler A and cooler B, if the latter includes a 4000 fan that sounds like a jet engine while the former is inaudible in a closed case?

Review packaging but not noise?

[btempleton]

I mean it just seems to me to be ridiculous to have detailed review of the packaging of all these coolers, and to pick a winner on something we'll throw out, but not to measure one of the most important factors in choosing a cooler -- noise levels.

I just can't fathom why the packaging review, it makes me suspect the motives of the whole thing.

What about dust?

[justthinkit]

I've have a (sucky) Dell desktop and when it is clean inside it runs quietly, even at 100% CPU load. Then as the days go by and the dog scratches his derriere repeatedly the fan noise rises. After about 10 days to two weeks I have to shut it down, vacuum it thoroughly inside and it is quiet once again.

So, how do these coolers perform with some dust in them? That is the cooler I want for the increased uptime.

Frustratingly misguided

[Gordo_1]

Ok, why would anyone spend $50+ to buy one of these monstrosities? Two reasons:

1. You want safe overclocked performance from the latest Core2Duo processors
2. You want a 'quiet' CPU cooling solution

This review utterly failed to achieve either end-user goal because they failed to even attempt to control variables, among other problems. Instead they:

1. Completely ignored noise as an issue. Sure the winning heatsink has huge heat pipes and all, but does its built-in fan sound like a jet engine to achieve its mark?
2. Did not standardize on a single 3rd-party fan to control for the huge variance in quality from one manufacturer to another.
3. Did not standardize on a single high performance thermal compound, but rather used whatever cheap goo each manufacturer stuck in the box.
4. No indication whether any of the extra cooling performance achieved by the top sinks actually has any positive effect on overclockability (aside from noise, the only other reason why you might reasonably consider one of these heatsinks). Many overclockers fail to achieve >50% overclocks of Core2Duo due to voltage regulation, memory or chipset cooling issues, independent of CPU cooling. For example, if your motherboard can't maintain a consistent voltage for the CPU under load, it doesn't matter that your heatsink achieves -270 degrees Kelvin.

So, in summary, all I've found out is which retail combination keeps my CPU coolest, irregardless of noise and whether the extra cooling performance actually matters. Hmmmm...great. IMHO, if you need to buy one of these things (like I did a while back) do yourself a favor and go read http://www.silentpcreview.com/ [silentpcreview.com] . They're a lot more scientific about their methodology.

Im all for site trying to make money from ad's, really I am. But 120 pages? LOADED with ads. Thats just insane.

Damn, who needs this shit anyway? Here, me do:

Most people use whatever stock cooler they get when they buy the CPU, which in this day and age is both reasonably quiet and keeps your CPU reasonably cool, without either the need to actively monitor or actively tweak it.

People who want a faster gaming rig buy faster graphics cards and more graphics cards.
People who want more CPU power buy faster CPUs and more cores.

Ignoring for the moment the bare few whose environmental conditions /really/ warrant custom cooling, most people I've met who buy this shit ar

That last one looks interesting. My wifi/dsl boxes are using 30W and probably cost just as much. Can't do anything with them either since I don't want to brick them trying to install custom firmware or anything.

Toothbrush

[Tribbin]

You greatly reduce the noise production by, twice every year, wiping all dust off the cooler-fans and fan-blades (especially onderneath where it's hard to reach) with a toothbrush (not your own).

You 'll be surprised.

1st place - Thermaltake Big Typ VX

2nd place - Scythe Miné
3rd place - Tuniq Tower 120
4th place - Titan Amanda
5th place - Zalman 9700

wow what a waste of time comparison

[llZENll]

i feel sorry for the reviewer, what a moron, comparing coolers using different fans is pretty much useless. you can make almost any of the heatsinks listed either a super quite poor performer, or a jet engine sounding super cooling machine, all by changing the fan. whats more, not including dB measurements in a review of HSFs today is laughable, whats the point.

the real measurement of a heatsink by most enthusiasts standards today lies in a perfect balance of cooling+silence, do yourself a favor and read

a better idea

Rather than suffer through more than 100 pages (WTF?) of advertisements and bad testing, I'd like to refer all of you to this simple page:

The Dan's Data CPU Cooler Snap Judgement Guide [dansdata.com]

It's about five years old, but the thermodynamic problem of removing waste heat from an object is about the same as it has ever been.

interesting

[webmonkey44]

High end users will find this interesting, I think.

Anybody got the pagecount on that one? 150 pages? seriously... I tested over 150 HSF so far; latest roundups are for AMD/INTEL's latest CPUs Roundup of HSF of 2006 http://www.madshrimps.be/?action=getarticle&artic I D=519 [madshrimps.be] Roundup of HSF 2007 P1 http://www.madshrimps.be/gotoartik.php?articID=556 [madshrimps.be] currently adding 8 more to the list, closing in on 200 HSF tested; and all this in less than 150+ pages per article...

sorry, misread

[bryan1945]

but I really thought that the title implied that someone was trying to put 25 coolers on one chip.

That by itself would be pretty neat, though.

[nbowman]

because the quality of them tends to be pretty mediocre at best. PS, there is no goddamn way I am gonna mount anything near the size of that TT cooler on a motherboard without using a backplate. seriously wtf TT?
