Poor i7 WC temps

SBB · 10-26-2009, 04:34 PM

D-Tek Fuzion v1 with 1366 mount kit and AS5
Themochill 120.3 rad + Scythe high flow fans
Liang D5 Vario Pump
1/2" hose all round

Getting poor temps .... got an i7 920 with a modest OC, and it idles around 45 and loads up to about 80 ... I tried at stock and the temps hardly change, surely they should be better than this?

Any ideas?

Thanks in advance
Ben

What are you ambient temps, do you have a gpu in the loop, what order are your components in the loop?

SBB · 10-26-2009, 04:47 PM

No GPU in the loop, just CPU, ambient temps are probably about average room temp, 21-23 degrees or so, it's going pump > rad > cpu > res

remount?

vcore?

dylskee · 10-26-2009, 05:10 PM

I'm in the same situation my friend!! I've got a pretty good water cooling setup and have tried remounting several times to no avail! My Idle temps are in the 40s and load temps are high 80s to low 90s. My Vcore is 1.26875 but even at stock my temps are high.

What cases do you guys have? It makes a huge difference in my experience. My soon to be replaced A05B with the radiator inside loads 91-92, took it out and loads 72ish tops on a Black Ice GT Stealth 240 / GTZ combo. i7 920 4.1ghz 1.280 vcore.

Your idle temps are not to awful bad, but those load temps are pretty crazy. I would try what the other poster said first, remount. Also try disabling HT just to see if it makes a difference. Could just be that ya got a lemon.

My 920 does 4ghz on stock voltage, idles at 33c and loads at 54c. Thats with 2 320's and two GPU's in the loop.

SBB · 10-26-2009, 05:59 PM

I can't remember my clocked vcore off hand, but increasing it from stock volts makes no real difference to temps. I'm going to remount tomorrow if I get chance, will let you know how I get on.

As for case, i've got a Lian LI PC-A70 full tower, with the rad mounted at the top, so it shouldnt be a problem.

There are definitely some dodgy 920s on the market, have seen some wildly different performances in similar chips recently. Hope you haven't got a duff

check VAPOR's I7 waterblock review revisited it shows the Dtek blocks need a mount mod to run i7 the right way that or you need a heat killer or apogee XT

millertime359 · 10-26-2009, 06:57 PM

I would upgrade your block to the Swiftech XT. I would think you would see a few degrees on improvement off of it.

vcore affects the temps alot... unless your vcore is under 1.5v i wouldn't worry about the vcore...

there are some corei7 with high current leakage..those run hot..like my core 920

Even though it's actually for the FuZion V2.

+1

I've got a TJ07 with great airflow and nice fans so I'm certain I wouldn't see much of a difference with the rads outside the case. I'm actually still in the fine tuning stage of this build so I don't even have the sides on the case yet.

I'm looking for a lot more than a few degrees!

I actually just ordered another 920 so I'll see if it's just a hot chip or my waterblock.

I was more refering to the OP.

The GTZ should be performing better than the fuzion V1, but if you are looking for lowest temps you can get, a HK or Swiftech XT might not be a bad idea.

Your buying a new 920 looking for lower temps, so a block upgrade doesn't seem unreasonable.

Please let us know how the new chip works out, I'm curious if this is a trend as of late, seeing a lot of these posts lately.

Edit, that goes for the OP too. ; )

It's a great clocking chip, just a hot SOB and it's driving me nuts not knowing why. I'm out of things to sell to buy another block but I would love to grab a Nickel HK!!

Will do, should have it by the end of the week I would think.

I'm actually a bit surprised that I haven't seen any on the FS section. I would of expected to see at least one with the release of the XT.

Is the XT supposed to perform better than the HK?

Vapor has it by a degree on a regular 920. Another review I guess shows the HK by a degree on a lapped 920.

Not huge gains, but there still was a lot of talk here about swapping out HKs for them. NTM, it seems a few guys around here buy CPU blocks like certain woman buy shoes.

Are you sure about your ambients? You should actually take a thermometer and put it right where your radiators take in air.

I have my computer underneath my desk. The ambient temperature of my room is usually around 25c. However the air right by my computer, the air my radiators are taking in is often 35c.

If you have high ambient temperatures that could be a big factor in your high CPU temperatures.

+1, depending on where your case is, it is probably intaking warmer than ambient air due to the heat not being able to escape from the case, this happened to me when I used to keep my tower under the desk. I could always feel hot air rising from under my desk. Also have to take the internal case temp into consideration if your internal rad exhausts air out of the case.

It really helps to know your ambient room temperature and the actual temperature of the air entering your radiator as they are not always the same.

Got the new chip today and this one runs hotter so I think I have a cooling issue here. Not to threadjack the OP's thread I put my results in my original thread found HERE.

Have you had any luck with your temps Ben?
