TECing a HD

I'm window-shopping (hm, that's actually a quite correct/good term, even in this day and age

for cooling and was told about TEC's in another forum here...

Currently I have one huge 120 fan, blowing air through four disks (actually, I have three of these setups) which is a bit noisy.

But I was planning on putting a huge 545W to cool the CPU and then one 45W per HD instead of all the fans...

But is 45W to much to cool a HD?

There is room for an extra PSU in the case to drive all the TEC's...

that 545W TEC you are talking about is not exactly a 545W its skewed info from ebay sellers as far as i know the largest TEC you can get is a 62x62 437W TEC and dont really know the heat output of a HDD so hopefully one of the many TECers or TEC savy

members of this forum can come in here to help you out with that

Instead of getting TEC's for the HDD's just buy a better fan that doesn't make as much noise. You do know you have to cool the TEC's hot side to?

I totally agree you would have mount a heatsink and fan to the hot side of the TEC I hav'nt heard of a TEC being used to cool a HD and where on the hard drive would you mount it on thin sheet top of the drive LOL

LOL...they have really got you on the run here haven't they.... Oh boy...It would be funny if it was not so potentially tragic...they quoted the input power it actually pumps about 266w at 27ÂºC and that's max not the value you will get running this thing in real world !! You are probably looking 180-200w.

I hope you realize a TEC is not a complete package you need a seperate power supply (especially for this one !) and a complete normal water cooling loop just to cool the hotside, It's useful to have a controller, a relay etc....the list goes on....

Firstly how ever low the power of the TEC's when the drives are idle and there is no load on the TEC they will go certainly go subambient and most likely cause internal condensation on the drives. No prizes for guessing what will happen then....
If you were to insist on using a TEC's for HD's you would need a heatsink/fan assembly on the the hotside of each one...well to be honest you might get away with a just a good heatsink with a low thermal resistance and one fan blowing the lot.
Either way you will not be in much of a better boat than you are already.

Unfortunately with TEC's a little window-shopping is no where near good enough to serously intend to use TEC's.

TECing your HDs is way to much work to be useful. And, afterall, the google study showed that HDs have the greatest MTBF at 37C.

Yup, read it here: http://labs.google.com/papers/disk_failures.pdf

A cold hard drive is BAD!!!!

As I said TEC'ing the HD wont work anyway due to the internal condensation it will produce.

DuckieHO that big post was it on here ? ...I'd like to read it...
