Watercooling woes for a Mini-ITX build

HalfBakedJake · 12 Nov 2014 at 14:42

Hi Guys,

I'm looking at building myself a watercooled ITX rig but had a few questions regarding heat dissipation.

The build will be in a Bitfenix Prodigy case and the items to be included in the loop are as follows.

CPU: Intel i7 7790k
GPU: Nvidia GTX 980

I was wondering if anyone had an idea of what the minimum amount of radiators I would need for this build. Ideally I want this to be a pretty silent build to the slower the RPM the better.

I was thinking 2x EK-CoolStream-RAD XT one with Push pull and the other just Push. Would this be overkill for my needs?

Any help would be greatly appreciated!

a 240mm rad would be sufficient.

here's me running an 3770k and a 7990 in a watercooled prodigy: http://forums.overclockers.co.uk/showthread.php?t=18564041

Did you pump die a heat death in the end?

Im running the same as you mate, 4790k, and a 980, i went with a 240mm rad in the top and a 180 in the front. but i had to buy a new 240 for the top as my old rad was too thick and wouldn't fit, its still tight now as both rads are touching.

I didn't want to settle for just a single 240 rad in the top.

Thanks guys,

So are you getting silent performance with that setup eggcup?

Not "silent" but its a hell of a lot quieter than with stock fans i tell ya.

When I originally built my new rig (coming from a 800D watercooled) I wasn't going to go water cooling as I thought the 980 reference cooler was going to be quite quiet but after a week I could'nt stand it any longer and had to go custom water. The difference is night and day.

Thats good to hear, I have a Fractal Define r4 at the moment and I get a loud hum. DOnt think its the fans but probs the CPU cooler.

As it will be sitting on my desk I want it to be as silent as possible. would you recommend a PWM pump? D5 or DDC?

Variable speed d5
