    Do I need to cool this WD HDD?


    I have 2 drives inside my desktop tower PC. A 512GB 850 Pro Samsung SSD and a WD Black 12TB spinning drive. Typical temperatures are ~43C for the SSD, 50-52C for the WD. I see the WD specs say operating range of 5-55; so mine is at the upper end of this range. I'm not seeing any errors in the SMART data.

    Should I try to find ways of lowering the temperature? There is a fair amount of open space in the PC with no components especially near the drive. I've wondered about attaching an HDD fan cooler but can't find one actually available.

    Any suggestions? Or am I worrying unnecessarily?

    Sounds like you might need to re-locate that 2TB hard drive, closer to a case fan if possible.
    I have the exact same 2TB WD hard drive.

    I keep my computer room cool... 16C. Even in use, the temp only goes up 2-3C

    WD 4TB Caviar Black FZBX
    WD 2TB Caviar Black FZEX


    Might be a dust build up. Could be bad location in computer case.
    I have quite a few WD Black 1TB, 2TB etc., they all run just about the same temps.

    Generally you want the case airflow with front and bottom as intakes, and top and rear as exhausts.
    It doesn't say what case case you have, so I can't really suggest an arrangement for the fans and drives.

    Thanks for that. Wow, what a tidy PC!

    My PC case is a generic Gigabyte one (similar to this Just a moment... ) and is reliant on passive cooling. The only fans are for the PSU (recently replaced as the fan on the old PSU was getting noisy) and for the processor, there is no case fan. This is the rear view

    and the side panel view - behind the upper vent is a duct to the processor fan

    It would seem to me that a fan can be attached to the rear panel and set to pull air through the cabinet, presumably the bottom of the side, and out through the back. If so I just need to measure the size of fan needed - from the holes there look to be 2 options.

    The MB has SYS_FAN1 & PWR_FAN, both 3 pin connectors; SYS_FAN2 is 4 pin. The MB manual says it supports CPU fan speed control, makes no mention of speed control for SYS_FAN2 though I'd hope that the Sense pin would be so used. My preference would be for a speed-controlled fan.

    Does this sound like a plan?

    FWIW I've been running with the side panel removed for the past hour or two and the 2 drive temperatures are 30C (SSD) & 40C (HDD), much better.

    Yeah, get at least an exhaust in there.

    I run a simple intake and exhaust, both at very low speed.

    In an 80F room, HDD temps are typically in the 30s.

    Although....the correlation between drive failure and temps is on the shaky side.

    Those fan mounts may be 92 mm. You'd prefer 120 or 140, but you are stuck with whatever your case has.

    Decide if you are noise conscious. A 92 mm fan has to spin fairly fast to move much air, but you shouldn't need to move a lot. Some fans are a lot quieter than others.

    SysFan2 likely supports PWM fans. If it does, buy a PWM. If not, an ordinary fixed speed 3 pin fan will do.

    You'll have to deal with fan cable lengths. SysFan2 may be too far from the exhaust mount. Use whatever the cable will reach.

    Spend maybe 20 at most.

    You might also want to look on the inside of the case behind the lower section of the front panel. You might be surprised to find a fan mounting location there. I agree that you definitely need more forced air circulation. The exhaust fan at a minimum.

    @tpriest

    Yeah, the back fan looks to be 92mm. If you can find one, I'd recommend this one...
    Cooler Master Blade Master 54.8 CFM 92 mm Fan (R4-BM9S-28PK-R0) - PCPartPicker

    That is a 4pin PWM fan...if the sys fan connectors on your motherboard are 4 pin, then you can probably control the fan speed in the BIOS.

    As @NavyLCDR said, there is probably at minimum one fan mount in the front.
    On cheap cases like that, there are probably clips holding the front of the case on. You should be able to open that.





    This isn't your case, but it should be similar. You can see how the front pulls off. Be careful, there may be wires attached to the part that pulls off.

    Behind the part that pulls off you should see 1 or 2 fan mounts.

    Here's a pic of another case with a similar front piece. The RED dots show the holes where the clips go in.
    And on this case there's two front fan mounts.
    On some cases the front doesn't "pop" off. On those type, you would have to mount the front fans from the inside.

    Try to get a rear fan and two front fans if you can mount two in the front. Then you will also be able to remove the side air duct. With a front intake and rear exhaust, you won't need the air duct.

    You will have to measure the size of the front fans. They might not be 92mm like the rear fan.

    The MB is a Gigabyte GA-P55-USB3. The manual refers to PWM for the CPU fan and the CPU fan pin details have Pin 4 as Speed Control.

    For PWR & SYS fans (both 3-pin), pin 1 is Ground, pin 2 is +12V, pin3 is Sense.

    For the 4-pin SYS_FAN2, pins 1 is Ground, pin 2 is +12V/Speed Control, pin 3 is Sense, pin 4 is Reserve.

    Does this mean that SYS_FAN2 has PWM / speed control?

    The rear panel fan mounting holes are approx. 70mm or 82mm, so a 92mm fan will be appropriate. There's no fan provision on the front panel but I can see there's provision for a fan on the base of the case, not keen on an intake there.

    Any thoughts on the least noisy fans? Prefer ones with rubber or otherwise insulated mounts to avoid transmission of vibration to the case.

    I know.

    Could you take a pic of the inside of your case? Like the pic of my case up above?

    That's an LGA 1156 motherboard.

    At least 10 years old.

    As I recall, PWM functionality that long ago was a bit testy.

    I wouldn't assume you can easily get it working. Maybe. Maybe not.

    As far as I know, a PWM fan will nonetheless function even if connected to a 3 pin mount.

    Quiet-ish fans:

    Certain Scythe models, including "Gentle Typhoon".

    Most any Noctua.

    But..........92 mm will have to spin fairly high to do much. All the more reason to go for a quiet model. A garden variety 92mm is likely to be annoying at 1500 rpm, maybe even 1000.

    So you may end up saying 800 rpm is all I can tolerate, even though drive temps are still 45 rather than the hoped for 35.

    If it's drive temps that are your major concern, maybe an intake would be better than an exhaust if the intake would blow directly over the drive.

    You'll have to experiment.

    Even a single speed 3 pin fan at 800 rpm is likely to make a difference, whether intake or exhaust. You just need to get stuff moving around inside.

    I am surprised it didn't come with fan


    • System Fan (front): One 120 mm silent fan
    • System Fan (rear): One 120 mm silent fan
