abnormally high cpu temps?

[raghavjindal]

so i just finished my first completely independent build (yay!) with the following specs

 

i7 4790 (stock cooler)

gigabyte z97n-wifi (i know, locked processor on a z97 motherboard, but this was the only lga 1150 mini itx motherboard available)

8 gb *1 corsair value select ddr3

gtx 960 (non gaming edition from msi)

2*256 gb adata ssd (dont know the exact model number)

corsair cx600m

all of this plus an Optical drive in a bitfenix prodigy m case

 

i boot it into the bios normally (no problems till here) and going to the "classic mode" it shows the cpu temp at 65 C rising steadily and at the point when it hits 80 C i shut it down to prevent any damage. i dont know if it will rise further. this is when the ambient temperature is below 25 C. on removing the side panel the cpu temp holds steady at 45 C.

 

i have removed one of the included two bitfenix fans as the motherboard only has one fan header apart from cpu fan. the remaining bottom mounted fan is configured as intake. i am using stock thermal compound on the cpu cooler and have made sure that the case fan and the cpu fan are both running.

 

could it be the poor cable management restricting airflow, or maybe the bad thermal compound? i need help.

 

PS: i havent yet installed an operating system out of fear of ruining the cpu.

My first 4790k went to 90c on the stock cooler! I rma d it and got a cooler also. Haven't had any issues since. With the side panel off it shouldn't be that much of a difference, unless your cable management is like a hoarders house. Or it could be that the cpu cooler isn't entirely seated to the cpu completely. The cooler should have just popped into the holes you only turn the pin deals to take the cooler off and there's the possibility it's a bad cpu...

did you overclock it? the temp difference with the side panels off is what convinced me that it isnt a bad cpu. the cooler is properly seated in the holes. the pins have tiny little heads popping out the back. should i remove the cooler and reinstall it?

Mine was stock speeds. You can try to remove and reinstall the cooler, but if it doesn't lower I'd recommend rma ing it or getting an aftermarket cooler. If you get the aftermarket cooler the cpu could still be bad. So it's up to you to decide

[Paranoid Kami]

It's probably just not seated correctly. Remove it, redo the thermal compound and reseat it. Had it happen to me before.

[raghavjindal]

So I'll redo the cooler with a new aftermarket thermal compound. And is just one fan enough for the case or should I buy a splitter and plug the other one in as well?

[Br3tt96]

One fan for the whole case is awful...

[Paranoid Kami]

You can buy a splitter for a dollar or two, which is under the cost of the fan you already have. Would help a lot for air flow.

[raghavjindal]

I guess I'll go to the local computer store today then.

Don't hate on one case fan...

I run my current build with only one exhaust fan, and everything runs below 60C even with the OC CPU on stock cooler

plus my room alone is about 75F

[Godlygamer23]

80C will not damage the CPU. It can 100C before shutting itself off.

[raghavjindal]

So I re applied the thermal paste put the cpu back in and did some cable management but now the PC won't boot at all. HELP

[raghavjindal]

Nvm. somehow after trying a dozen times it booted up randomly. I guess the atx cable was loose. Now my bios reads 51 degrees (Celsius of course) CPU temp which is a lot better than 75 but I am still not sure if this is normal?
