2500k very high temperature readings?

Question

Just built a new computer
gigabyte z68-ud3h-b3
i5 2500k
g skill 8gb ddr3 ram
560ti ds
seasonic 620w bronze certified
1tb 7200 rpm seagate hdd
sony optical drive
cm 690 ii advance

Using hw montior to look at temperatures
and intel stock cooler
one 120mm exhaust fan in the back
one 140 mm exhaust fan on top
two 120mm intake fans on side
one 140 mm intake fan in the front
Did not OC anything. Everything is at stock

On idle
Core #0 40c
Core #1 40c
Core #2 40c
Core #3 36c

When I tried to run bf3 they went
Core #0 98c
Core #1 98c
Core #2 98c
Core #3 93c

Can anyone help with this and why are the temperatures going so high???

Answer 1

Any software that reports more then one temperature for one processor (single OR multi-core) is bogus. Therefore, the temperature readings themselves are as such. If Gigabyte doesn't supply a BIOS-monitoring utility for THAT motherboard (and specific to a BIOS version), you can't trust any dynamic data reported by anything else. If it is a Gigabyte utility than download the most recent version.



UPDATE: Maybe the mouth-breather with the inverted thumb can explain how it is possible to thermally isolate cores in a multi-core CPU. Or maybe list the reasons that Intel or AMD would ever even think of such a thing. Chime in with your own answer. I bet it will be hilarious.

Answer 2

Either you haven't applied the thermal paste properly or you haven't attached the cooler properly. Turn it off and sort it out before you wreck your nice new processor. Another possibility is that the fan on the cooler isn't working or isn't plugged into the motherboard.



Edit: Despite the next answer if there's a problem with the thermal paste or the cooler's mounting then you'd expect the heat sink to be fairly cold, not hot. This would be because the processor isn't transferring it's heat to the cooler properly, so the processor gets hot and the cooler doesn't absorb it's heat. I doubt that it's a false reading as he suggests either.

Answer 3

i think its a false reading, i've had them on my i5 2500k and MSI p67 mobo. 98c is the TJmax, or max safe temp/shutdown trigger, i cant remember if it will run at 98 :/

I used coretemp for my measurements and even when idling(but not limited to), one minute it would be 34c, then suddenly jump to all cores 98!



saying that the 93c core seems funny. a good way to test is it touch the heatsink, if its too hot to touch then it could be actually overheating!
