Water Cooling didnt change my temps at all over air :(

1622 34
Hey guys, I finished setting up my WC loop today. I actually changed it, before the rad was mounted inside, then I put it outside the case, and the temps still are the exact same as when I was air cooling with the vendetta 2.


Earlier Loop (about 5 hours ago loop)

What would be causing me to have to temp change?

I have 3 fans on the rad. I ordered 4 Scythe Slip Stream Kaze Jyuni 120MM Fan 1200RPM 68.5CFM 24DBA

The loop consists of DD CPX-PRO --> MCR220 --> Apogee GTZ --> Temporary custom res --> back to pump

Yeah, the full cover GPU waterblocks like what you have on your 4850 are very restrictive. Not only is your GPU adding heat to the loop(which your radiators should be able to handle, and temps should only increase a couple degrees) but the flow rate is probably far from optimal, which reduces the performance of your cpu block as well as the radiators.

Also, I don't think your choice of fans is helping. I've heard that the Noctua fans don't perform well on radiators, and you're also using no-name fans as well. It may help to get some high static pressure fans that perform well on a radiator and use those instead.
