i7-950 stock temps - Page 3

post #21 of 35
I noticed you said you were pointing your sink straight up and down as opposed to front to back. With your graphics card also venting heat upwards I suspect you're pulling a lot of warm air through the fins and reducing the amount of heat transfer you're dissapating. Instead of allowing continuous flow from front to back and drawing your warmer video card air out the back (before going through your cpu fins as they're orientated now) you are instead quite likely "pulling" air quite forcefully off your graphics card through the fins thanks to a convincing push pull combination fan. To be quite honest, you may want to consider going back to a more conventional front to back orientation for your sink. At least then everything will flow much more freely through your case without having a big wad of vertical flow right in the middle- not only drawing warm air in through your sink but also creating eddies I don't think your case was designed to accommodate.

I notice your rear fan will be VERY close to your pull fan if you orientate it front to back like that but it's definitely worth a shot.

The only reason I oriented it that way was because when I put the cooler in it looked like the ram would be in the way of one of the fans if it was pointing to the rear. I might take off the HS on the ram to make some room, but I'll see if the cooler can fit pointed to the rear before I try that. When the TIM arrives I'll reorient the cooler, probably be a few days before that arrives though.

Sorry for the double post but I thought I'd add an update.

I reoriented the cooler to face out the rear, which actually fit better than vertical because of the tall ram heatsinks, but the result was essentially no change. I've also applied the MX-4 thermal paste and changed the HS back to it's original configuration, since I feel blowing hot air up will work better than trying to blow it out the rear. I've also ordered a Noctua NH-D14 cooler (since I had some store credit anyway), which should help with temps.

I've also OCd the 950 slightly, at 1.088V I've got it clocked to 3.45 GHz (23x150), with the temps around the same level as my pre-overclock levels.

dude i am having the same problem, my i7 950 idles around 43c an on full load 72c+ that to on stock frequency.
i am using an coolermaster hyper N620 with TX 2 thermal grease.

this is the link for my thread:

ppl say i7's run at high temps its normal, what's wrng with every1. i7's run cooler than my temps, bet on it :/

I'm not sure that it's all i7s that run hot, but it does seem that 950s do run hotter than 920s or 930s, at least from what I've read.

What voltage is your CPU set at? Mine came a little high at stock, lowering it helped with the temps a little. You might also need to reseat your heat sink, just in case there was an air bubble or a problem with the thermal paste.

How much paste do you use? About the size of a grain of rice is all you need. Sometimes just a bit more. Having your cooler oriented to blow the hot air out the back of your case is your best bet id say otherwise it will juts be circulating hot in your case.

Black Patriot, I'm in the same boat as you as my stock CPU idle temps are between 35-40C with the idle voltages between 0.94-1.00.

Confirm you first manually lowered your stock CPU voltages in the BIOS before attempting the 3.45GHz overclock (with the voltage at 1.088)?

If so, what did you lower the stock voltage to and how did it affect your temps? Thanks!

My case has 2 large vents with 140mm fans at the top, the heat goes straight out so it's not circulating in the case.

I did lower the voltage, though I can't remember what to, I think it was around 1V, maybe 1.05, something like that. There was no change to idle temps but load was 1-2C cooler because the mobo wasn't automatically stepping up the voltage.

My mobo (Asus Sabertooth X58) has an auto overclocking setting in the BIOS where you can choose either stock, 3.33GHz, or 3.7GHz. Well, I just tried the 3.7GHz option, ran Prime 95 for about 10 minutes and the load temps went up to 77C (idle was about 50C)!

This concerns me a bit because I was under the impression that the Noctua NH-D14 was one of the best air coolers on the market, but I'm not seeing the results. In case you were wondering, my ambient temps are about 25C, I've reseated the heatsink using only about a "grain of rice" amount of thermal paste (the paste included with the cooler), and I have the CPU fans blowing the air out the back of the case (as opposed to blowing the the air up).

Any thoughts on why my temps are so high?
