Fans are at 75% and the pc is on idle.

40 deg for the CPU, NB & Mosfets?

Should my temps be better?

The only thing i cant think of is to much thermal compound perhaps?

here is a screen bellow

perhaps accurate system specs and some relevant information?

If you are trying to cool your CPU, chipsets, Mosfets with just a 120mm and a slow fan then yes you might have issues.

But again, more information, or pics!

Is it the same setup you have here:

No offense Deadly, you did a wonderful job but I would be a little concerned with the position of your vid res. Maybe I'm not seeing it right but it looks to me as it's system pressure transfering the coolant towards your pump and not gravity... IDK :confused:

Do NOT evaluate your temps at idle. Do a LinX or OCCT linpack run, and post a screenie during the run when the cpu is 100%. That's how we can tell if your temps are appropriate or not.

+1 to PaulieG, I heard that Intel's sensors are unreliable at low temps.

i hear, which is why it was so difficult to get the loop flowing, but i managed by sub-merging and tilting the case and res upside down.

those temps i believe are alright, 30-40's idle for the gpu

Looks good to me. I had a 120.3 just on my cpu and it idled upper 30s. I'm guessing your load temps reach mid to high 70's if not peaking just over 80 on maybe core 0.

Load test it and let see whats going on, if your way out of my speculation then I'll be surprised.

Exactly what I was saying. We can only evaluate with load temps.

I was just wondering because my single loop (pump->rad->cpu->gpu->res) is running at 26C at idle and 36-38 at full load while gaming

well here is the a cpu stress test pic. i was stressing the gpu at the same time using Fur Bench and for the cpu prime95.

max temp is around 55 deg Celsius for the CPU @ 100% load

max temp is around 44 deg Celsius for the GPU @ 100% load

Don't use Coretemp, try out realtemp. But even if using Coretemp they still aren't that bad at all.

hmm, well my gpu is 4870x2 and hitting about 44 deg celsius @ 100% load which is being cooled by a danger den WB and tfx 240 rad with 2 enermax fans.

what kind of rad do you have cooling your whole loop?

Don't forget loosenut, you are also on a 955BE which they run a little bit cooler.

True.

Don't get me wrong everyone, I'm not trying to win a pissing contest here. I just wanted to point out my concern for the positioning of his GPU res.

I still think he did a phenominal job at putting all this together in such limited space and for that I applaud you Deadly :toast:

You mean 3X2GB right?

Just like everyone already said, get your load temps and then go from there;)

NVM, I saw that you already did. Not really bad temps IMHO.

I have my i7's at 4.0ghz, water cooled on an open bench (Sunbeam Ultra). Your temps are a little high, as mine are similar to yours despite a 4.0ghz OC and 1.27v. Try overclocking yours slightly, maybe around 3.6ghz and try for 1.24v or so, then run LinX. That will give us a better idea. My loop consists of:

EK Supreme HF
EK Coolstream 240 rad
655 Vario pump
Gentle Typhoon 1150 RPM's

I'm only cooling the CPU right now.

so u have 5 120mm fans pushing air out + psu? or is the cpu radiator's 3 fans pulling air in?<--if not, then maybe try reversing them to pull air in instead of pushimg it out!

i got a a xchanger 360 on the top cooling the MB + CPU with 3x Panaflo fans


an xchanger 240 on the bottom cooling the GPU with 2x enermax fans


all fans a pushing air through the rad out of the case
