High temps on i7 920 D0

Hello all,

Just got a used i7 920 D0 (had a new C0 before). I have a Thermalright IFx-14 cpu cooler attached with the default TIM. Now, the problem is that the i7 is at stock (2.66ghz) with HT on (C1E and EIST) off, but the temps i am getting are on a higher side. It idles at 45-47c and at 100% load it touches 80 or more. With that, i am even scared to overclock it as the temps would reach 60+ idle at 3.6ghz and 90+ when priming when ambience is 26-30!

To sort this issue, I previously had a Biostar X58 on which i had the same problem, hence i went for Gigabyte X58 Ud5 on which I still have the same issue. I've reseated the IFX umpteen number of times with different TIM's (AS5, TX2, MX2 etc) and still the same issue. This high temp issue is also seen on the stock cooler@ stock speeds.

Now, what could be the problem? Is it the CPU, the cooler or the motherboard :??: 

Please help!

My system config is below :
Core i7 920 - (2.66ghz) with HT on (C1E and EIST off)
Gskill PC12800 6GB triple channelled.
Gigabyte EX58 UD5
EVGA GTX260

Do let me know if ya'll need anymore information, ill be glad to provide :) 

Regards,
Anish

Those cpus run warm, but they're tough. If you're not having any lock-ups, artifacts, or bluescreens, then you may be fine. These are 130w cpus, not as cool running as older cpus. Check the Intel specs; you may be within the normal running range. With the retail boxed cpus, you have a 3 year warranty, so relax. By then, you'll be ready for a new cpu.

I have not yet encountered any lockups at stock or when overclocked to 3.6ghz. But it does get locked up due to high temps after i prime for a couple of mins and that is exactly when the temps are really high like 99+ (i am not kidding!).

I had built an exact replica of my system for one of my cousins' and his temps are near 32-35 idle at stock, thats like a difference of 10deg! Also, other friends who have the SLBEJ (D0's) have lower temps than mine.

Temps seem a little warm - my own i7 920 runs 33/34 most of the time idle and 42/43 under load.

What case are you using and what intake / exhaust fans do you have as these can drastically affect your cooling

mine runs:
Mugen 2 100% fan speed:
36'C idle, 53'C load @ prime95

CM N520 100% fan speed:
38'C idle, 57'C load @ prime95

i would have to agree that seems a bit extreme. what voltage are you running it on? pretty decent temps at stock 34 /35 idle and 50 at full load
I would normally say to simply reseat it but you already have and changed motherboards, but you may have just simply gotten a bad chip

My i7 920 (C0 I think, got it a year ago) has the exact same issue! It gets up to 99c when I p95 test it, and this is with a good aftermarket cooler. I have no idea why it is doing this, and no one has been able to give me a solution. I have a full ATX case with amazing airflow, so that is not the issue. Maybe we should contact Intel about this, since the TC is the third person I have seen with these unexplainable high temperatures on an i7.

I am running it on stock. Just my rams have been overclocked to 1600mhz which they were rated to run.
What if its really a bad chip. Can i opt for RMA? I have the box too.

I am using NZXT Lexa Blueline. There is one Xigmatek XLF1254 65CFM fan at the rear exhaust which sucks out some air and there is one 115CFM panny which is fitted right in between the IFX-14 which is also in the same configuration as the latter.

That's weird. My RAM sticks are overclocked to 1600MHz as well. I am going to try to underclock them and see if any difference is made.

I might be wrong but, doesn't overclocking the RAM past 1066MHz (the max supported speed by i7 920) cause the CPU to overclock as well?

Not really, my CPU is resting well at 2.66ghz but I've only enabled the XMP Profile1 which takes my rams to 1600mhz with a 3200mhz uncore and 1.6v (XMP1 preset)
