Pelt and Fans?

RedPhoenix · 09-06-2003, 01:53 PM

Alright, is it true for a pelt to work properly I need REALLY loud, fast, high cfm fans? I cant just use quiet fans for my rad?

Procore Rad and I want a Enermax 120mm adjustable fan
Rad also uses intake air too.

Do.... I .... Need.... High... CFM... Fans.... to.... use... A.... Pelt.... Properly...?

It depends if your rad is up too the job of removing the right amount of heat with slow fans running off of it..

Can´t see why you must have large fans, but if you have a small rad larger fans are needed too cool adequatly.

Build a shroud for the rad and put two fans on either side of it.

That'll increase the efficiency of the rad even if you use low voltage fan(s).

I am trying a heatpipe pelt combo. I have not built it yet cuz I can't find a salvaged dehumidifier with a good heat pipe.

Why would a dehumidifier have a heat pipe exactly? Its got a compressor/condensor/evaporator and works the same as a freezer. No heat pipes there, theyre fairly uncommon infact, could salvage a small one from an old laptop...

Theres a Hard drive cooler that has 10heatpipes

I was told that some dehumidifiers DO use heat pipes. Try an HVAC place; they should have a source for them copycat.

If you look to industrial applications then you'll find that radiators and in fact all cooling devices are typically listed as "will cool x watts to y degrees". This is because the temp you'll see with the cooling depends on the heat load you are dealing with. So if you throw a 226W peltier into the loop, you will find that the existing rad/fan will no longer cool the water to ~5C above room temperature and instead the water temp is maybe 12C over room temp. Look at the deltaT max across your peltier, and then use maybe 12-15C over room temp as your hot side temp. That dictates to a large extent how cold the cold side will get.

How to get the water cooler? Bigger rad or bigger fans of course (or add less heat).

I dont think your gonna have a meltdown with a slow fan but you aren't gonna get the most out of your pelt investment.

For what? And why if they already have a compressor?

I'm about to try a 172W TEC in my passive watercooling rig. Water is great at removing heat. Radiators work well shifting large temperature differentials. I anticipate my heatercore will get toasty hot but the TEC will hold a sufficient temperature standoff from the CPU.

So, no I don't think TECs require large fast fans just adequate watercooling to take the heat away to your radiator.
