hl0m4n · 08-01-2010, 07:24 PM

i currently have a koolance exos water cooling system. do the 3 fans need to blow air to the radiator or out? currently all 3 fans are drawing air out... i thought it was supposed to draw air in to cool the radiator?

help much appreciated, thanks guys.

If they drew air in, you would be picking up heat from the radiator and dumping it into the case which would almost be like positive feedback (Your case would get warmer and warmer causing your cooling system to work harder and harder). You want to reject that heat outside the case, so it sounds like they are operating properly.

The fans need to blow air out through the radiator.
