View Full Version : Best Cooling Solution for Rad?

09-17-05, 10:04 PM
I got a dilemma in which way to mount the radiator for my Thermaltake Big Water WC set-up. I'm getting the Antec P180 and it has a 120mm fan on top so I'm thinking of using that one. Now which would give the rad the best cooling.. Option 1 or Option 2?


I guess the other options on where to mount it is the rear exhaust fan but I thought that fan would benefit more for keeping the vid cards cooler if I don't replace it with the rad. And I wanna try to not mount it outside and keep everything inside the case.

I was always told you want to "pull" air across the rad(fig1). Also using a cowl between your rad and fan will give you even better performance.

Keep in mind your rad will get dirty, so you want a place that will offer easy access to cleaning.

good luck

Yeah I was hoping that the little air-duct filter the P180 comes with, will keep most of the dust off the rad so it won't get as dirty.

BTW, what do you mean a cowl?

Is that radiator fan in intake or exhaust? It should be an exhaust, and figure 2 would be the better option.

Seeing as most cars have behind the rad, sucking the air through, I think thats the best way. Also for the fan you might want something like this.

Well at stock, the Thermaltake Rad has it's fan like in Option 2, to be blowing air through the rad and come out the other side through the case vent holes. So I guess I should just leave it the way it comes @ stock.

Just to add, my Exos 2 blows air out the top, thus pulling air through the radiator like what Aphot mentioned.

Hmm so I'm still confused which would give me the best results, Option 1 or 2.... I was surfing the Post your Rigs thread and someone has the BigWater kit with the rad mounted on top and the fan pulling the air from it like in Option 1:

Option 2 is the better option. Option 1 disrupts airflow.

Remember, all fans at the top you want to be exhausts, all fans on the bottom of the case are intakes. And exhast at the top of your case will cool the radiator, and get rid of extra heat in the case. And intake at the top will cool your radiator. And disrupt airflow :)
