I have a Corsair H50 water cooler on my rig and I want to refill the water, replace thermal paste, clean radiator, all that maintenance stuff. I just don't know how to drain and refill the cooler, I have it out of my system and I have distilled water. What should I do, should I even drain it? I'm not sure how long the water has been in there because I bought this pc secondhand.

Quick qeustion, I got the new paste on and i think it should work, but which way whold I have the fan go on the radiator? should I pull air through or push is out. in other words, which way should the air go through the radiator and what side of the radiator should the fan be placed?

Tried both and was most successful pulling cool air in. I have a large top exhaust which I turned up the speed on. Now I'm getting about 4 degrees less at idle in a hotter room compared to last night and the AC5 hasn't even been through 4 hours of its "set time." Hopefully I'll get a bit lower before I go for a higher overclock. Thanks guys
