Hello.
My system has a strange problem. From a cold boot, temperatures are around 78c in BIOS and a bit less in Windows. Any sort of demanding usage puts me in the 90c range and AIDA64 throttles within seconds.
However, if I sleep the computer then reawaken it everything is fine. Idle temps are in the mid 20's and AIDA 64 happily stresses the CPU and FPU around 60c with rare spikes towards the 70's over an hour. I left my pc on last night an it was idling at around 20c when I looked at it.
If I reboot then everything is still fine, including my BIOS temps. However if I turn the pc off again then my heat problems return until I do a sleep/resume. I have tested this at least 20 times so I am confident that once it has slept everything is safe to use.
If I reflash the BIOS to the original version then the sleep/resume trick doesn't work.
I think (but it doesn't happen everytime) that HWMON only gets a reading from my +12v rail after I have slept and resumed. It never gets this reading from a cold boot. Other than this there are no differences between HWMON and BIOS settings/stats when coming from a cold boot vs having slept/resumed.
Naturally I am keen to sort this out by returning the faulty part for a replacement but I'm not sure how to isolate it as I only have access to my stepson's pc with is a Z77 system.
My specs are:
4790k@stock
Gigabyte Z97n wifi
Kingston Hyper Beast 2400 c11 (2x8gb)
Corsair H60
Silverstone SG05 case with 450w PSU
Crucial MX100
Windows 8.1
My suspiscion is that it's either the motherboard or the PSU but I can only test the PSU, not the motherboard.
Things I have tried:
Rebuilding the pc from scratch, making sure there are no bad connections or shorts
Reflashing the BIOS, returning to original BIOS, resetting CMOS and clearing CMOS battery
Things I've yet to try
A different PSU.
Using the other 12v ATX socket on the PSU. Is this safe? It would fit but the connectors "foolproof" arrangement aren't identical.
Going back to the stock cooler in case the H60 is somehow at fault (doubting this)/
I'm not sure what a sleep/wake cycle actually does but maybe that clue is enough for one of you to know what's going on?
Thanks very much for your help.
