Are these temperatures normal?

[SovietKitsch]

I know this is a stupid question to ask since I'm slightly behind the latest tech, but are my temperatures normal?

I just have a Black Ice SR1 quad rad with 4 Gentle Typhoons at 1850RPM for my two GTX 480's (Yes, I know) and a Core i7 920 D0 @ 4.0Ghz (1.375v). I'm going to be putting on a motherbord block very shortly for the E760 as this motherboard gets really stupidly hot.

My temps on the i7 at idle are around 34-39C, and under most normal computer games 50c, however stress testing and GTA 4 can raise that to a very warm 70C.

The 480's are normally very good, idle they sit at 40 and in game they never really go above 50, but in GTA4 they can do 60, sometimes 70. I don't even think they get that hot on Furmark.

My question is this; am I nitpicking too much or can I expect more? The air that gets thrown out of the rad is still pretty warm and easily makes my room 10F-15F hotter than the rest of the house, and I want something that isn't going to bake me in the summer. I was thinking of doing a single loop for the i7 920 and the motherboard block while having the 480's on the quad rad, how would that affect temperatures? Does anyone have any advice or suggestions? Thanks!

Your temperatures are normal, just what one would expect with such a setup.
The dual loop vs single loop has been debated a lot, i would suggest trying to find Gabe's threads about that he did an excellent work providing full data and tests.

Low FPI rad with high (relatively) speed fans? Try a tighter finned radiator that will properly take advantage of those fans like a HWL GTX or a ThermoChill for some improvement in temps.

Looks like only about 1c differnece. Not really worth the cost to swap imo

Those temperatures are ok, maybe a wee bit high. Two off those GPUs can easily take care of of tripple. So that leaves the CPU with not much head room. Adding more rad might drop your temps a degree or two but prolly not worth the effort.

Yes just changing the radiator will be much hassle for very little result at all.
Only answer is, MORE RADIATORS (now where is the Spartaa smiley that Waterlogged brought up)

-only [[easily makes my room 10F-15F hotter than the rest of the house]] my air temps going to the external rads were 29-32c in a room [8x10'] that started out @ 21c
-I just cut a cold air return[4x10"] in the floor behind the computer with a booster fan[in duct with a 12v relay on-off with computer pwr] to pull the heat dump to the basement ,worked well , but then figured why not move the heat source out of the room now that I have a hole in my oak floor so I moved my 2 x 320's [+1] downstairs\under floor[with second pump] .water temps 25c under load so far not a lot of testing yet.

Thanks for the info everyone.

I'm pulling air from the inside of the case through the rad out the side panel, would be pulling fresh air into the rad from outside the case be better?

And I know the answer is always MORE RAD, and I was thinking of putting a 1x120 or 2x120 down there to help cope with the O/C i7, the question would be would be even if it's not its own loop, would throwing another rad help drop temps any? It'd effectively would be 6x120, or am I missing the point completely?

Yes, another radiator would drop your temps some, but it wont be a drastic. If you don't have a push pull config then add some spare fans and see what happens. If you don't have any lying around your best bet is another rad. What is your ambient? ith 22c 65 would be decent load temps. Your ambient might just be high.

You do know your room temps won't change one teeny bit with more rad?

Your temps are fine as is, you could do better with more rad though. If you add a rad, do the heatload and DT math to see how much your DT drops.

For example, if your have a 120x3 and your DT is 10C and you add a 120x1 your DT will drop by about 2.5 C, possibly a bit less.

You mean this?

If you really want a better delta i'd say Dual loop + more rad surface, wont yield you much better results but atleast you'll be closer to ambients if anything..
