Hard Drive Cooling for 10 Cents 420

David Tiberio writes "I've bought many hard drive cooling solutions over the years, sometimes spending $50 or more on drive cooling systems that were noisy and did little to cool down the drive. After much tinkering, I discovered a simple solution that cost me only 10 cents per drive... the 1/2 inch bracket. Mounts any 80mm fan to the belly of an internal hard drive."

      You have to take the fan out of the power supply to put on the hard drive bracket and then swap the case fan with the power supply fan because your power supply is over-heating and then go out and purchase a case fan because your system is getting too warm.

      So essentially. the hard drive fan is free. It is the case fan that costs you some dough...

The heat is in the drive mechanism itself; you cool it by cooling the sides and top of the case.

      The magnetic field produced by a small DC fan might not be enough to faze the platter. It takes a magnetic field of a certain strength to make a change in the data bits.

      I have a few Compaq Xeon workstations that placed the drives transversely in front of the system power supply so cooling air can pass between the drives. I have yet to see a problem. It's designed to cool 15k RPM drives very quietly. The PSU fan itself is a slower 12cm fan, placed on the intake of the PSU, only a few cm away from the drive's edges. It's very quiet for a PC, and very impressively quiet for a system with a 15k RPM drive in it.

    Well... Most S.M.A.R.T. temperature sensors are on the PCB and they are measuring PCB temperature instead of the internal drive temperature.

    Hence, a fan under the disk makes a lot of difference while making very little to make your data safer.

    A 3x 40mm fan battery in front of a drive or a pressed enclosure that cools the actual package holding the platters makes a lot of difference there while not chaning the S.M.A.R.T. reading by more then a degree or so.

    It is up to you - what do you want. Show (a good reading) or substance (good temperature of your drive platters and heads).

      Yeah. LOL. It's not the PCB that gets hot anyway, at least not on my drives.

      The heat is in the disc, the drive motor, and related surfaces. Some of them can get quite hot. I still have some (working!) giant SCSI bricks that get hot enough to burn flesh.

      Full height 5.25 drives that would burn fingers and break your foot too, if you dropped it. I think it weighs close to 10 pounds. It'd probably still work after the fall but it only holds 1 gig or something. Not worth a bother.

      Anyway, I cool my drives with a 120v turbine fan that blows sideways across the whole drive. The air cools the disc side and the PCB side. Works great. Doesn't tax the system PSU.
      • can you explain why to blow air onto the HDD, instead of of blowing the air away?

        • For what it's worth, try holding your hand in the airflow of a fan some time. It feels a lot stronger on the side the fan blows on to compared to the one the fan sucks the air from. Obviously, the same amount of air has to be blown out as sucked in, but blewn out air is accelerated in a certain direction giving it more power. It's not that much of a difference, anyway - people who experiment with switching on their CPU heatsink/fan typically end up with only a few degrees of temperature difference. Most mod

        I have been lead to understand that drives don't typically fail because their platters got hot. They tend to fail because their circuit boards fail. You'll find advice all over the internet suggesting that you try to fix a broken drive by swapping the circuit board from another of the same model before purchasing expensive data reclamation.

        In that context, this fellow's solution doesn't seem so irrelevant. Keeping the circuit board cool is likely to lengthen the life of the drive.
    • Quoting the article: "Please note that in some cases I suspected that the drive temperature was not being reported properly, as some drives showed no change in temperature via software but were clearly cooler to the touch." I assume he touched the metal around the actual platters and not the (powered) drive electronics. I doubt a 3x 40 mm fan battery will be more effective than this, in fact it'd probably be more noisy at the same amount of airflow/cooling. It's not like his setup only cooled the PCB.

    If you decide to go with this kind of setup, try to make sure you use a fan with low vibration (well balanced, low speed). The last thing you need with a hard drive is more vibration. The drive head is only flying a few hundred molecules above the drive surface.

    It may not amount to much as the vibration needs to be of the right frequency to be really bad. But it is probably better to err on the side of caution with drive lifetimes already being as bad as they are.

    I personally use a 120mm fan that is mounted on rubber pegs, perpendicular to the hard drives, but not mounted to the drives themselves. This way, less vibration is transferred to the drives.

    1. Running 2 drives as RAID-1 with a spare souunds less efficient than just running RAID-1 for the OS partition and RAID-5 for the data. RAID-5 is faster for writes than RAID-1, but RAID-1 offers protection for the boot OS

    2. One fan per drive seems inefficient, and it will increase the power consumption of the box as a whole - not including the wasted space.

    3. Mounting a large fan with one single bracket would make the fam vibrate and not be mounted in a sturdy fashion

    4. The title doesn't include the cost of the fans. If he has three drives, three fans, three brackets, we're looking at about $20

    5. All these extra fans brings us back to the age of the noisy PC. So passé.

    My suggestion? A good Antec case with proper ventilation holes at the front and a 120mm fan at the rear. If you have three or more drives, add an 80mm fan at the front, blowing air on the drives in the same direction the air is pulled in from the 120mm. It's not the low temp of the drives that matters, it's air circulation + consistent temp.

    I also tried mounting a fan to my hard drive with an angle bracket. I found out that you need to be really careful about how deep you drill and tap the mounting holes into the drive.

    I used 1/2-inch deep holes, and the drive wouldn't even fire up when I tried to boot. It turned out that the drive had really flimsy construction, and they had moving parts right under the surface that were immobilized by the screws. The cheap POS wouldn't even work after I took the screws back out.

    If you plan to do this, I'd recommend using very short screws; probably no more than 1/8-inch.

  • Instead of just arranging the components in a way that doesn't let excess heat build up, we're making the system use even more power to push air around in an enclosed space. This is not how you make a more efficient system. If your hard drive is that hot, you're using the wrong chassis. Get one designed with airflow in mind. Put a heat sink on the hot components, or, better yet, figure out why they're turning so much of the power they draw into heat instead of something useful. Recycle your old chassis. No

    2. With some superglue on the end of the toothpick, insert it in the hole so that it sticks to the spindle
    3. Glue the blade to the other end of the toothpick.

    Now you see, no need for a fan. As long as your drive's running, the fan blade you just installed will be spinning at 5400 (or whatever rpm) your drive is.

    Much cheaper than $0.10.

  • better to put the fan on the side. then you can use one fan to cool more than one drive.

    I have a 80mm fan right now cooling 4 ide drives and it brings the temps down about 10-15 degrees C. They run about 35-37 degrees C as opposed to almost 50 degrees C without it.

    pretty basic hack really. I don't see the point in making a WHOLE slashdot article about it. Maybe someone out there just went, "Hey, what a GREAT idea." but I bet that person already tried to dunk their drives in ice water.

    An MIT prof just released a new book that you can read online [mit.edu] called Democratizing Innovation. I haven't read the whole thing yet but it looks like he may be on to something. Also see Pro-Am Revolution [demos.co.uk].

    Grrrr!

    HD's dont need cooling. I've never cooled my HD's and not ever had a HD problem in 20+ years I've had a computer.

    This cooling fad is just another way of companies selling you expensive crap you don't technically need (such as fans with leds).

    The author is probably one of those people who pay 200 bucks for gold speaker cables too.

    Big Mistake in the article: Use only nylon straps as brackets. A metal strap conducts the fan vibration to the hard drive.

    This is a great idea if all you needed to do was cool the circuit board. The fans don't effectively cool the platters, though, and sometimes that thermistor that tells you the temperature is mounted on the same side as the circuit board, getting cooled by that fan, and showing you lower temperatures, but the platters are still running hot.
