Let me preface this by telling you all that I do NOT know a lot about the inner workings of computers, and am not currently trying to overclock my cpu. I am posting this here because from reading various threads it seems like you might have the combined knowledge to help me figure this out.
Recently I began monitoring my core temps, using coretemp and speedfan, on a whim, and found I was idling around 58c on my i7 930 2.8ghz. Obviously, even to someone who knows very little, this seemed bonkers.
So I opened her up, (this is not a custom rig, this is an HP pavilion from 2010), and used compressed air to blow out all the dust. In the process I found what could be best described as a dryer lint sheet worth of dust packed on the back of my heatsink between it and the fan. I managed to remove it all without unseating the heatsink, checked to make sure it wasn't loose (as far as I can tell it isn't) and booted her back up.
The idle temps are down to around 38c-44c (I'm using speedfan to keep my 2 fans cranked to 100% all the time because now I'm neurotic).
I ran a stress test to see what the result would be, and in prime95 under 100% load it gets up to 90c + in under a minute. Not good.
I know the stock heatsink is probably crappy, and I should get a new one, but here's the part I'm finding really weird.
I read that if your vcore is too high, it can also cause elevated temps, so I went to check my vcore, and HP BIOS has absolutely 0 options for anything (yay HP). Speedfan won't show my voltage, cpu-z wont show my voltage, hwmonitor has 3 catergoris VIN0, VIN1, VIN2, all at 1.6, but no vcore and OCCT has the same VINs, all at 1.6 and voltage graph shows it steady at 1.6. If that really is the voltage, isn't that insanely high for a stock i7 2.8?
So after all that, what would be the best option for lowering these crazy temps, would it be a new heatsink/re-seating? Would it be lowering the vcore (through magic apparently)? I'm at a loss.
