I7 930 serious heat problem!!

Hi guys, I'm in need of serious help

Here's my rig

i7 930
DFI x58 T3H6 m-atx
2x5850 in xfire config
750w PSU
CoolerMaster Hyper N520
CoolerMaster Thermal Paste

k here's the problem:
I am currently overclocking my i7-930 to 4.2ghz at 1.325v set in the bios

The idle temp is 45-48 using CoreTemp
Room temp around 20C

When I stress it with Prime95, the temp goes up to 97-100 but it never doesn't reboot
I've had it run for 5mins and it runs stable, but I turned it off because I am scared that it might damage my cpu

I've reseated my cooler and cleaned both the stand and cpu with Alcohol and reapplied the Thermal Paste for 3 times already, and the temp has only reduced by 2-3C
I used the cross method with not too much paste, I am sure I applied it correctly

I used the exact same cooler and paste for my previous 955BE overclocked to 3.8ghz and the temp was under 60C at full load stable

So wth is the problem, I am really fustrated
Is it my cooler? My Thermal Paste? The voltage?

Please help me

Yes, you will damage it if you keep running it at 100c.

Buy a GOOD cooler, NH-D14/Megahalems, if you want to OC that far on air. The 955BE didn't put out anywhere near as much heat as an OCed i7 @ 4.2 Ghz.

Good temps on high OC's requires several things:

Case w/ Good Airflow - With twin GPU's and 4 GHz, I would not consider anything less than a full tower case. HAF 932 and Antec 1200 are the consensus favs.

Great PSU - Stable OC's require stable voltages and this only comes with a high quality PSU...think Antec SG or CP, Corsair HX, Seasonic X series.

Great MoBo Power Regulation - Low end MoBos don't provide this. Want to make sure you have an enthusiast level mobo w/ superior power regulation. With stable PSU feeds, this allows stable OC's at lower voltages which means leSS HEAT.

Top Notch HSF System - 4 GHz easily doable with air cooling provided you have a quality heat sink, twin fans in push-pull configuration and top notch TIM. I'd suggest:

Pick from the top 3 or 4 here:

pick a TIM from the top 3 or 4 here:

Here's what I am using both for performance and ease of installation....was tempted to move to the new Noctua RJR suggested but the 3 pound weight scared me off. Here's what I'm putting in new builds Mega w/ IC Diamond TIM and twin Scythe PWMfans (make sure ya MoBo can handle the fan wattage). ($65 for the HS, $7 for TIM, $11 each for two PWM fans and $7 for a Y cable splitter).

http://www.frozencpu.com/products/10026/fan-639/Scythe_...

My son's box has a 920 in the Antec 1200 (fans at 2/3 speed for quietness) w/ SG-850, Asus R2E, Prolimatech Megashadow, IC Diamond TIM, twin Enermax Magma fans and it has core temps of 70-74 under OCCT CPU test loads at 4.4 Ghz (1.30 volts)

Very nice post and agree. You know also some CPU's even if you have enough cooling requirments might not overclock that far for the fact that CPU's thread are all different and might not be able to hold up that wattage even if the box or specs of that CPU say that. I had a AMD Black Edition that was suppose to OC easy and it was a standard 3.0Ghz, but even with water cooling and enough fans it would only go to 3.4Ghz for the fact that the CPU wouldn't support that amount of wattage. Sorry about your problems though if you need anything else just ask us. Thanks.

Thank you very much for all your replies
I'm going to buy a new case next week, I was going to anyways
And a new PSU within the next month
But the thing about the Mobo is, I just bought it like 1 week ago, and it was still quite expensive, for me anyways, I'll hold off the mobo for now, just hoping it doens't fry my cpu.

Oh yea one more thing, my extra fans sucking out heat from the back is going nuts
It keeps reving up and down with the rpms, anyone know why?

OMG, you think the answer to your CPU overheating problem is your mobo?

Have fun with your computer :sarcastic:

Nah, the problem should be my cpu heatsink and the overall case area
should I start looking into water cooling? lol

The reason for fans RPM's changing at a constant rate is the BIOS controlling heat/rpm ratio. The more heat the faster the rpm's.

The heat is probably due to the CPU threads and the fact that maybe one of the CPU's that can't be overclocked that far.

I mean even if you have the best cooling in the world your CPU will only go so far!

You must factor in (Motherboard)(CPU type and stock voltages/ghz)(PSU)(Cooling).

Question:

Is it running hot at stock clock speeds?

No my cpu doesn't run too hot at stock speeds
35ish at Idle
60ish at Fullload

One thing I notice is that my north bridge runs hot when I OC it to 4.2ghz

Here is a slight conclusion

My board is a piece of crap, it's the cheapest x58board avalible

My PSU is a piece of crap, it's a 750w with only 1 6pin (yes I'm using six 4 pins to get my 5850s to work, but it is stable never the less)

My Heatsink is not the best out there, but it is one of the more expensive ones

My thermal glue is the cheapest out of brand names

........ I'm gonna run my rig at stock for now, until I buy a new case/PSU/board next month, and mayb switch to a watercooling solution later

I don't know how many ways I can say this, YOUR COOLER IS NOT UP TO HANDLING AN OCed i7.

Review from a YEAR ago (47 coolers beat it, better ones out today): http://www.frostytech.com/articleview.cfm?articleid=239...

Here is with an i7 (FAIL, Megahalems 14c lower @ 3.8 Ghz): http://www.hardwarecanucks.com/forum/hardware-canucks-r...

And when you say you might go water, I presume you are talking about a custom water cooling system and not one of these small all-in-one jobs because the high end air beats those also.

Yes a custom water system, not crappy ones
Just need to do a *** load more homework before I make one

Thank you RJR, for pointing out SO MANY TIMES I HAVE A SHITTY COOLER

No seriously, thank u =P

I don't see anything wrong here with your CPU or CPU cooler. Everything could normal and proper. You're pushing all four cores, 8 threads to its maximum (pedal to metal) of course it's gonna glow red hot if it could.

What kind of CPU fan profile are you using? What are the rpms of the CPU cooler, is it maxed out?

Good thing you don't play Prime95. What are the CPUs during normal gaming?

You're pushing for an extreme overclock on air. You can buy a $100 CPU cooler but if your case is retaining heat, especial dual 5850's, it won't make much of a difference.

I would check the airflow first. On Prime 95, does it make a difference in the temps if the case side panel is out" If so, then you have an airflow (lack of) problem.

The CPU cooler is only as good as the internal case ambient temperature.

Well I'm glad your factoring in everything you will need to do OCing succesful and your going to buy everything you need. Anyways if you need any more help just ask.

-Thanks man.
