First WC attempt, how are my temps?

So, after months (actually years) of thinking and researching, I finally decided to try out water cooling. None of that closed loop crap, but real water cooling. I had been resistant in the past, due to lack of knowledge. But last few weeks I've been reading up on it and slowly buying the components.

Yesterday I got finished with my first WC attempt. And here are my results. I am only cooling CPU and GPU.

The CPU is Intel i7-980X (OC'd to 4.4GHz) and the GPU is HIS Radeon HD6990 4GB.
Testing was done with prime 95 and Skyrim game just to test GPU heat.


Before water cooling:
CPU idle: 35-40C
CPU Load: 75-80C (after only 15min of prime95)
GPU idle 40C (30% fan speed)
GPU load 65-67C (75% leaf blower speed)

After water cooling:
CPU idle: 26-31C
CPU Load: 58-65C (after 3hrs of prime95)
GPU idle 32-34C
GPU load 50-53C

Since I have no experience with water cooling, I don't really know what I should get. But I can say that I am extremely satisfied with the results so far.

What do you guys think?
 
So you say your happy? Thats all that matters then :)

Seriously though, those are really good temps and you should be happy!
 
Are the temps what they should be?

I am interested in overclocking the GPU, but every time I try, my computer freezes. I've read online that my card should be able to handle good overclocks, but mine doesn't. Don't know why.
 
Really stress out the GPUs with something like Unigine Heaven benchmark.

Although those temps look pretty good to me.

Without knowing what WC hardware you have and your ambient temps that's kind of a hard questino to answer ;).

Ambient temp: 23C

Pump: Swiftech MCP655 Variable speed
Res: Koolance 450X2
Rad 1: XSPC EX360 Crossflow with 3 of these fans in push
Rad 2: XSPS RS120 with this fan in pull
CPU Block: Alphacool NexXxoS X² Bold HIGHFLOW
GPU Block: Heatkiller GPU-X³ 6990 -Hole Edition

My order is:
Res>Pump>360 Rad>CPU>120 Rad>GPU>Res

Kind of decent results, right?

The single fan is way, way too loud and will be changed, but that was the only 120 I had available.

The fans you're using also has a significant effect on the temps you see.

I had a 6990 with a 920 (runs hotter than your 980x) on a 3x140 radiator with 3 1500 RPM fans. Those 6990 temps are about the same as mine.

There, now I posted the fans :)
 
Just changed the water in my system (had to change some of the tubing) and added some PT Nuke and here are my new results:

Before water cooling:
CPU idle: 35-40C
CPU Load: 75-80C (after only 15min of prime95)
GPU idle: 40C (30% fan speed)
GPU load: 65-67C (75% leaf blower speed)

After water cooling:
CPU idle: 22-29C
CPU Load: 55-62C (after 3hrs of prime95)
GPU idle: 30-32C
GPU load: 42C (after 2.5hrs of skyrim)

As you can see, CRAZY drop in GPU temps! Even CPU temps dropped. Maybe it's because the thermal compounds have started to settle.
