Cpu temp 80 deg celsius at bios

[Ronan_]

Pls help.. I have a core i7 2600 @ 3.4 ghz on an p8h61-m, 8 gig ddr, geforce gtx 560ti oc, at bios, my cpu reads 80 deg celsius.. Sometimes i cant boot my pc or when i start games, it reboots the pc.. What shoul i do?

You should start by reseating your cooler and reapplying new thermal paste.

Thanks for your fast reply, but im just wondering, can a virus cause a faulty high cpu temps at bios?

extremely unlikely.

Thanks! Ill try to reseat with a new thermal paste soon.. Can 80 deg celsius cpu temp enough to cause crashes? And reboots? Not really sure if the high temp really is the cause of my crashes.. I had the same symptoms a couple of months ago, but it spontaneously resolved, now im having it again..

If it is 80°c at the BIOS, with zero load on the CPU, then I'm pretty damn certain it's hitting a lot higher than that in Windows which would absolutely cause it to crash.

Thanks, but how much can a thermal paste lower cpu temps? Can an 80 deg celsius be lowered to 40s with just a thermal paste alone? Or is there something else thats causing it to heat up that high? Should i do or check something else?

There are numerous things that can cause it.

Poor airflow through case.
Blocked air vents.
Dried out thermal paste.
Poor quality CPU cooler.
High ambient (room) temperatures.

I'd need to know what case you have, how many fans, what the normal room temperature is, and what CPU cooler you have. Then we could work out exactly what might be causing your problem.

Thank u very much! I just have a morrlogic futura 220 casing, nothin special w my casing, just 1 fan behind the casing, just the stock fan from intel i7. Room temp is around 27 deg celsius well ventilated room. But when i was looking at the temp in the bios i removed the side panel of the casing, so i dont think lack of casing fans is the issue, just an update, i reapplied the dried out thermal paste with just a generic one, and it read around 60deg celsius maxing at 65 at bios. Is that ok?

Though i still have the problem that might help u help me. Hehe! Everytime i go into a game like nba 2k16, the screen would go black with multicolored pixels flickering all over my screen, then it reboots the pc sometimes it does not. Could this be a gpu problem now? Or is my cpu still overheats at 65 deg celsius in bios? Thank u in advance!!

If your CPU is sitting at 65°c just in the BIOS then you still have a severe over heating issue. You should be sitting at absolutely no more than 35-40°c in BIOS, which is essentially the same as sitting just on the desktop. As soon as you start placing strain on the CPU it will over heat to the point where the CPU will shut the PC down.

You say you only have one case fan, and a stock intel cooler. That clearly is not enough. You need a better CPU cooler, and having seen what your case looks like, I would advise picking up a new one with better cooling options.

Thank u so much for that very quick reply. Should i consider a PSU or a GPU problem? It seems that the crash happens when i play games, i had this pc setup and casing for at least 3-5 years already, and had no problems before.. Is the PSU starting fail and causing my cpu to overheat? I downloaded HWMonitor to see diff temp readings, but im not really sure how to read this and can this help me pinpoint the problem? Thanks again in advance! How can i send u a monitoring data from hwmonitor?

Go buy some artic silver 5, or EK thermal paste.
1) Clean off the top of the CPU and bottom of your heatsink with Isoproyl alcohol 70% or higher
2) apply 2 thin lines of thermal paste (imagine dividing your cpu into 3rds) and make your lines there, stopping a bit before the edge. (with thermal paste your don't want to put too much)
3)place the Heatsink directly on top of the cpu going straight down.
4)give the heatsink a very gentle twist back and forth without lifting it up
5) bolt the heatsink down.
6) restart computer, check temps
