What's acceptable for water temperature?

[Goose]

I've finally got my first custom loop up and running and I dont actually know what an acceptable temperature is for the water.

Cooling my system (see sig) is an EK D5 PWM pump, Black Ice 360 GTS, Black Ice 360 GTR (I think, its the 60mm thick multi port one) with Corsair ML120's on both rads.

I've left Heaven running for about 15 minutes now and the temps are as follows;

Water: Fluctuating between 36-39c
GPU: Around 40C
CPU: Around 44-50c (which i dont understand since its only at about 10% load).

The above temps are achieved with all 6 fans at 1000rpm and the pump at 3600rpm.

I'm a bit concerned that when i start gaming and the CPU comes under the load the above temps are going up pretty sharply.

Thanks

While gaming the water temp seems to top out at about 41c. Is that too high? I'm using Mayhems soft tubing FWIW.

To put things into perspective, if you own a small aquarium, during summer months ambient room temp is enough to keep the water 26c tropical without the need of a heater.

By the time you add 600w for PC components, 40c is pretty good going.

Mayhems will have a spec sheet but I wouldn’t worry about it.

Ok, thanks for putting my mind at ease

How come you choose the Black Ice 360 GTR? That radiator is for high speed fans of 1500rpm and over and is pretty useless with low speed fans. A GTX would have been a better choice.

I couldn't remember exactly which models my rads are. One is an SR2 Xtreme+ 360 and the other is a 360 GTS.

How high do they go compared to idle, though?
My system idles at about 36ºC in warm weather, pump and fans are always at max... but when running graphics-heavy stuff and benchmarks it only goes up by 8ºC. Not amazing, but I have naff-all airflow into the room anyway and usually keep the window shut against thripps.

Since starting this thread things have changed a little. I didn't actually have my case panels on and after attaching them the water temp during gaming was getting as high as 48c with the fans running at 1300rpm.

Now that ambient temps have dropped my water temp at idle is around 30c and gaming is 40-42c. I'm not too worried about those temps although i take it that 10-12c above ambient isn't exactly great? I'm wondering if my Corsair ML120's aren't the best radiator fans.

The temps I posted originally were from a game that wasn't actually pushing my GPU to 100% and after now playing Anno 1800 things are bit a different.

Depending on the ambient temp my water temp is anything from 40-50c and thats with the pump at 100% and fans at 1200rpm. I'm actually a little disappointed at how fast i have to have the fans to keep the water temp below 50c.

@pastymuncher

Case is a Lian Li O11 Dynamic, SR2 Rad is mounted up top, GTS mounted on the side, all fans set to pull. Loop order is Pump/res (its an EK all-in-one thing)>side rad>top rad>CPU>GPU>pump/res. I'm confident i didn't mix up any of the in/outs but i'll double check when i get some free time.

I dont think push/pull would work due to space constraints and I dont really feel like taking my loop apart after the ordeal I went through getting it all together.

No idea what "supercruise" is?

Made one small tweak and removed the dust filters (DEMCiflex ones that i paid a fortune for) and water temp is now at around 38c with the fans at 1000rpm. I guess DEMCiflex filters aren't all they're made out to be.
