Hi Mick,
I'll try that once I put it all back together.

Hi Mick,
I'll try that once I put it all back together.
Cheers,
I have put the computer again together and I am running tests before I plug in more accessories or run more software. Good news is I haven't yet seen the earlier problem, which is great although I am still testing.
I am testing with a Vanilla W7 and the case is open, one thing that is worrying my is that the i7 CPU is hitting about 97-98C in full load and about 28C idle. Is that temperature what is expected with the stock heat sink and fan? Maybe i need to reply the thermal paste, would appreciate your advise. Let me know if this is normal.
Thanks,

Yes I am running with the BIOS unmodified (as received) and I can see it's running stock speed.
Thanks. I will try that, last time i applied thermal compound the size of a pea, I'll see how it distributed and perhaps apply more this time.
Unfortunately there was just about the same quantity of the thermal compound that I received so I don't think it was any better after i took the cooler off, re-applied thermal compound and put the cooler back.
If anything it is a bit worse. The readings of temperature idle are now at 30-32C and under load at 97-98C.
Some pictures below of how the CPU and the cooler look before I re-applied the thermal compound. Does that coverage look right?
Do you guys think there is a problem with the CPU or is this just a matter of applying more compound next time?
Out of thermal paste now ...

The amount of compound on the CPU seems about right, I usually recommend customers apply the compound on the CPU to resemble the number five on a dice and then attach the cooler so the compound is evenly spread, too much compound will have a negative impact on cooling though.
Can you advise which program you are using to view the temperatures and how are you testing the CPU under load?
Kind regards,
For load I was using OCCT ( http://www.ocbase.com/perestroika_en/index.php ) and heavyload.
For checking the temperature I was using gigabyte own tool as well as core temp. And some others I can't remember right now.
Would higher than expected temperature indicate a faulty CPU? Did the testers check the temperature during the testing?
emilio,
When mounting the cooler are you 100% sure that all four push pins have gone through the motherboard? I normally recommend mounting these types of coolers when the board is outside of the case to ensure that the cooler is correctly installed.
Can you also advise if you kept a record of the CPU temperatures before returning the components?
The engineer did not report any issues concerning the CPU temperature, but I do not believe the tests carried out would cause anywhere near the level of stress that OCCT generates.
If you run the system under load with prime95 are you getting similar temperatures?
Kind regards,
I run the same test before and also saw high temperatures (90+) although at the time I didn't think this was related as the system would reboot under low temperatures as well.
Yes all 4 pins went in but I was thinking the stock cooler might need more thermal compound as it came with quite a bit more on it.
In you experience have you seen faulty CPU showing high temperature? At this stage I am happy to buy another cooler if we think this one isn't working, I just want to get the computer working again.
In terms of recommending coolers can you give me some options that would fit in my case (Silverstone Fortress FT03B).
The memory is relatively close to the CPU and I am not sure which ones fit, if you give me a list I can pick, looking for something quiet and not too expensive.
emilio,
It has been known that a faulty CPU can cause high temperatures. When running the chip under load have you had CPU-Z open to see if this chip is dropping its multiplier? This will normally happen if this chip is reaching its thermal threshold. I would also recommend updating the motherboard bios to the latest version if you have not already done so.
The LN40975 Akasa Venom Pico CPU Cooler should be suitable for the memory you are using, or a cooler such as the Corsair H40 or H60 etc.
With the case you are using, you need to ensure that the intake fans are pulling enough air into the system, you may need to increase the fan rpm profile within the bios.
Kind regards,
I could see the CPU frequency higher and then dropping as it got hot.
The case is open as in the photo, and the room is cool.
I'll check the recommended coolers.
Mick, thanks for your help.
As for air coolers, you only recommended the Akasa Venom PICO, is that because you think this is best or is that the only one that would fit with my case/motherboard/memory?
Would the Arctic Cooling Freezer 7 or 13 not be suitable?
Thanks, I ordered the Akasa Venom Pico as I am I think the Freezer 7 might have touched the memory.
Hope to get it tomorrow, try it out and rule our a CPU problem.
I'll let you know how the tests go after I installed the new cooler.
Is there any software I should use to monitor the temperature?
Hi Mick,
The order is placed, but I was checking the Akasa website and it only mentions i3 and i5

Can you confirm this is a good cooler for an i7? Did you check that with the sales team?
Thanks
