New 2600k hitting 66c in BIOS?

post #1 of 15
Thread Starter 
Hi all, I just put together my PC build last night and quickly noticed the CPU temperature hitting what I assume should be full load temperatures but I'm not sure exactly why this is.

I'm using the Asus P8P67 Deluxe mobo with an i7 2600k and just using the stock heatsink for now, (I'll get a better one in a week or so...just want to get the thing up and running for now).

Initially I didn't use my own Arcitc Silver paste, instead just going with what Intel had already applied onto the stock heatsink, but while sitting in BIOS the temperatures were quickly going up and up in to 70c, (It probably would have burnt itself out if I didn't shut off the PC). Today I cleaned off Intel's thermal paste and applied some of the Arctic Silver I had bought. Now the temperatures stabilize at about 66c, but isn't that still way too hot for just sitting in BIOS?

I haven't installed Windows yet because I want to make sure my temps are safe before doing anything that would raise the temps any more than they are now. Any ideas? I can re-apply the paste but I thought I did a decent job at getting just a pea dot size in the center of the heatsink, I also used 91% rubbing alcohol to clean the old goop off before applying the AC5.

I don't know what I'm doing wrong here and before I reapply the paste I wanted to post this question here first to get some advice.

Are you sure one of the pushpins isn't holding a corner of the heat sink off the proc? It sounds like the heat sink isn't making proper contact even after a re-seat.

Try to reset the BIOS as well? Apply more thermal paste than pea size?

Sorry, but what do you mean by resetting the BIOS?

I'll try reapplying the paste. As for the heatsink not being properly mounted that could be possible because the stock heatsink has the worst mounting method of any heatsink I've ever used. But when looking at the bottom side of the motherboard it does look like it is properly mounted.

I don't know if I should use any more thermal paste,( I was actually worried I might have used too much), but I will remove it and see how well it covered the CPU with the amount I used previously to at least see if I need more and by how much.

Does anybody know what my temperatures should be while navigating in BIOS? I read someone with a similar problem in another thread but some were saying BIOS actually causes 30-60% load on the processor, so I'm just curious what temperature range I should expect that would be "normal" when in the BIOS screen?

With the crappy stock cooler I was getting temps ~46c in BIOS which still seemed pretty high. After I swapped in my Thermaltake Silent, temps dropped to ~36c.

I'd be happy if my temps are 46c at idle, that's nothing to worry about. 66c at idle make me a good bit nervous though. I went ahead and reapplied the paste but my temps are now going up past 70c again. I don't know if I'm just not applying enough or what the deal is. When I took off the heatsink to reapply the paste was off center on the heatsink and almost oozed over onto my motherboard. That time I had put the paste on the heatsink itself but because the paste is so sticky it lifted up to form a hershy kiss form, which is why I think it went off center.

Sorry for the terribly blurry pictures, but here is a picture of the heatsink with the paste off center:


And here is what the CPU looked like with the paste almost oozing onto the motherboard:

Perhaps I did use just the right amount but because it formed a hershy kiss form decided to spread of center.


I used a tad bit less this next time but applied directly to the CPU, (might not have been enough which would explain higher temps). I'll take some more pictures when I take it off to see how it spread out, and maybe I can get some tips on better ways to apply. I feel like such a noob because this isn't my first CPU installation but I've never had a problem before.

The intel stock heatsink is terrible you need too buy off market heatsink. on my i5 2500k when i first installed it myTemperature was at 93C at idle I turned off the computer right away scared the **** out of me. i had push down the heatsink hard after that it works fine idle at 37C but when running prine 95 goes up to 70C.

Try using small amount thermal past cause the picture you post seems like you put to much thermal past.

that's way too much thermal paste, use about a pea size or grain of rice method and if you are using a stock cooler, spread out the paste with a plastic baggy turned inside out or something prior to pushing down on the push pins.

Good luck!

Use a bb size amount with the stock cooler. Pea is too much imho.

Try using a razor blade or credit card to spread a thin layer of thermal paste over the entire cpu. It might help. if not just wait for a better heatsink. stock heatsinks are terrible. one of my old intel ones let my cpu get up to 85c in bios. pos
