Hi,

 

I have a heat issue with 1 of 2 identical desktop, that tries its best to roast hard drives.

 

 

On #2, StableBit Scanner warns me the drives running temperature steadily climbing upward of 50c which is preset to send me an email.

From a overnight cold boot, they begin one by one to get in the 50c's within the hour ! 

 

The back-up server (#2) is an exact copy of the main server (#1).Back-up server (#2) runs only for incremental backup,I then shut it down

The main server (#1) runs about 18 hrs a day, then sleeps at night; Drives are usually running around 35c which is heaven for them

 

While I'm getting set to add two 120mm fans to the lower front as "standard option #1", I still wonder if it will be enough.

The projected 2 additional fans will draw fresh room air around the six lower 3.5" drive bays then into the case

The drives that are first to report being bbq'd are within the three 5.25" to 3.5" upper area.

Will they benefit at all from the new wind tunnel below?

 

A pic of my "bare" backup server. It's an Antec Three Hundred Two case.

I added ICY DOCK Flex-Fit 3.5" adapters to all three 5.25" bays.

"green" drives tend to run cooler, but 50c is pretty warm, I would look at replacing it, could possibly be failing bearings.  I tend to replace all of my drives every 2 or 3 years one at a time. But that's just me, and they are in a raid so its easy to do.

You definitely need to get fans mounted to the HD rack. If you can mount them behind, that would be best. Pull the air through the drives, not push. And get PWM fans. Get a fan controller that has heat probes or actually gets the HD temps from the system. You can attach the probes to the hottest HDs, and set the controller to adjust the fan speed based on those temps. My fan controller in the server just died, so I replaced it with this one. So far I'm very happy with it, much better than the one I had. All the settings are in an app that you install. It gives you quite a lot of control. The app used to get the drive temps from the system, but they removed that feature because apparently some people reported it was causing their drives to click. But it comes with 4 heat probes. I'm only using two. I've attached them to the two hottest drives. The readings are pretty close to the S.M.A.R.T. temps, within 1C. The fan control can be customized. I made a temp/speed curve that it follows. And because I'm using PWM fans, the speeds are accurately controlled. As the temp rises, the fans are sped up, little by little. It maintains the temp very well. These are the fans that I have.

I wouldn't think very much as the air is not actually moving across those drives.  Is there room to mount a fan on the back of the adapters to pull air across those drives?

I see where you're going with this and agree 100%, but in my case, I doubt nine blue and green WD would all fail simultaneously.

 Not really, I'm thinking more pass-thru adapters design such as this would improve airflow

That was the plan, pull cool air from room thru the drives, but the fans have only the front of the case to go to, there are already fan screw holes there (we see them in the pic above).

The back side is the hdd wires connection side, not the best spot for fans.

If you're only talking about the 5.25" adapter, I've used (it's sitting on my shelf) this one in the past. It has a fan built into it. It worked pretty well.

To me these are the problem reducing air flow on the drives.

Or you could use something like this.

Thanks @Doofus, I have bookmarked your amazon finds.

The trays I bought (ICY DOCK Flexfit Trio) seem to have a design flaw regarding airflow.

The 64k$ question remains: why 1 of 2 identical desktop overheat the drives and not the other :unsure:

Who knows. It might simply be environmental, or imperfections in the drives etc. Don't bang your head against the wall, over it.

Oh I forgot, I have one of these in use, right now. And it works really well. I did change the fan on the back to a noctua, though. It's quieter.

Oh its a whole PC worth of hot drives?   Do the fans show the correct RPM?  Check the power supply voltages as well. That's pretty much the only two things that would raise the temp of perfectly fine drives.  Other than adding fans which you are looking at doing.

For fan RPM, I remember seeing my the bios display: chassis fan1: 000 rpm / chassis fan2: 000 rpm (but no worries, the top and back fans are spinning quite normally). I should check how/where their wires connect to.

The PSU is a 3 month old bronze.

As I said, this case has provision for 2 front mounted 120mm fans. Logic would dictate they pull cool room air thru drives to the inside (to be exhausted by either of 2 out flowing back fans.

Are you saying I should exhaust from the front (as well as from back, 4 exhaust only, no intake (?) Please confirm.

You're talking about the fans mounting behind the case facia, right? So it'll pull air in from outside then push it through the hard drives?

air moves across the drives, front to back or back to front.  that's your goal.
