My Jump to Watercooling, how are temps?

[IceRedwing]

Well I'm curious how my temps are suppose to be like now that I jumped into watercooling.

The loop is cooling an E6400 "A" batch running at 3.4GHz at 1.56V (bios) 1.476 (load)
The Vdroop is really huge, so I don't know exactly how accurate it is, but all my programs that I use to measure the voltage are identical.

Inside the loop is also 2x 8800GTS-640MB

The loop looks something like this:

EK 150 Resevoir -> MCP355 Pump -> Swiftech 120.3 Radiator -> D-Tek FuZion Cpu waterblock -> Swiftech MCW60 GPU waterblock -> Black Ice Extreme 120.1 Radiator -> 2nd Swiftech MCW60 GPU waterblock -> Resevoir

At idle it is usually at 38-40C (CPU) and both GPU's are at 40C

At CPU Load (Orthos Blend) it goes up to 45C (max) , usually 42-43C
The cores max out at 60C each

The CPU & GPU don't really stray much from idle to load it seems. So I'm unsure if that is common. Even under Orthos Blend Run + ATI tool Stress run the temperatures remain consistent to what I posted. Is it possible to improve the temperatures? better order in the loop? Also if one of my fans in the 120.3 is a high performance 120mm, will it matter? (the other 2 are yates). The high performance fan is a thermaltake with a fan mate mounted outside for me to control.

A bit more information to add is that I live in Los Angeles, so ambient temps are pretty high. Normally 30+ celsius on a good day or a little higher on a really hot day heh. The case I'm using is a Coolermaster 832. The CM has a natural 120.2 mounting at the bottom (or 2x120mm holes if you want to view it that way). I simply cut the bottom to make more room to add another 120mm fan. Both radiators are sending air out of the case via 120mm(3) at the bottom mount and 120mm (1) at the back vent mount. The case has 2x120mm fans blowing air into the case from the front and from the top. Also the side of the CM 832 is nothing but mesh so air is probably going in through there. The entire loop (included both radiators) is internal as well.

Edit: Also I was thinking, if it would be more beneficial if I blew the air into the case (from the radiators) and have the 2 other 120mm fans in the front and the top as the exhaust? I figure the air outside would naturally be cooler than inside even with the mesh sides.

Those seem like great temps to be because your on a dual GPU loop.

Your Vcore is a bit high but those temps seem really great. Remember vcore of 1.45 REAL will push a tuniq tower in the 70's when loaded.

Also your gpu's not breaking very much, thtas a classic example of h2o cooling. On a GTX it will vary a bit more due to the more heat, but on my current setup, which is a 7900GT volt moded, the temps only rise at most 2-3C from load to idle.


Also if you want better temps, you need to split your system up. I think i told you thinks b4. But i dont see anything wrong with your current temps, and splitting them up would be more of a pain in your case.

AS for now, id be happy with what your getting. AT those voltages, your chip is doing wonderfully.


Last note: Rads become more efficient as the temps increase. So dont worry about the heat. AT most your temps will go up by 5-6C unless we get a 100F day. So you should be able to keep your overclocks.

Ah good to know.

I did mess around with it a little and reversed the fans on the radiators. All 4 fans on the radiators are pushing air into the case from the outside (versus pushing air inside the case out), The temperature of my motherboard increased by 5C (from 43C to 48C), which isn't part of the loop so it is air cooled. But the temperature of the CPU & GPU dropped 3C in max load. Oddly enough the idle temperature remained the same.

I added pictures to show how the loop is oriented. The 2 missing 120mm fans on the 120.3 radiator is mounted on the bottom (outside of the case) to keep the radiator locked in position

I like it. It works.
