Fan Direction

[markjonesx]

I'm building a new rig, it will have water cooling Thermochill PA120.3 rad.

Which way is the best for air flow;

1. Air inside the case blown over rad and out

2. Air inside the case sucked over rad and out

3. Air outside the case blown over rad and into case and out

4. Air outside the case sucked over rad and into case and out

Thanx in advance.

We need more info on your configuration. Are you talking about fans mounted on the rad or fans within the case itself? The ThermoChill PA120.3 is optimize for use with three fans mounted on the radiator in either a "push" or "pull" configuration. There's alot of debate over at Xtreme Systems as to which configuration is more effective and it may depend on a variety of individual factors such as radiator mounting, shroud design and, of course, the type of fans used.

I highly recommend the Extreme Systems liquid cooling forums for all your questions on water cooling. Unless, of course, aigomorla decides to pop in on this thread.

I used to design cooling systems in the Auto industry, pullers are always better on performance (you'll notice car radiators always sit behind the Rad). You also have to optimise the distance from the core, by testing.

Just wondered if there was any difference in computing?
