Uh oh, 70 C cpu temp on first boot?

[Darrvid]

Edit: I cleaned it, but it's running really hot. Check out my post a few down...



I applied way too much artic silver 5 to my heatsink and now have to clean it off after it's already been installed. I checked artics website (the instructions there let me know I did it wrong..) and they suggest isopropyl alcohol. Is that just rubbing alcohol?

Also, anyone have some tips with the stock Intel core2duo heatsinks? I had a hell of a time getting it installed, the pegs wouldn't stay in the MB. Now, I have to take it back out so hopefully I won't have to struggle so hard to get it installed this time.

Yes, it's rubbing alcohol.

I use 90% Isopropyl (rubbing) alcohol and it works fine. Some others have suggested using vodka or other liquids high in alcohol, but I just stick to the good old rubbing alcohol from a drug store.

Agreed. :thumbsup: 'Regular' isopropyl alcohol is typically 70% alcohol with water added to dilute its strength. OTOH, 90% or 91% alcohol is more pure, with less water, and should leave less of a residue after it dries.

Either way, it's prolly not critical which strength you use. In my experience, even 'regular' 70% isopropyl alcohol doesn't leave much residue on things that I clean with it. Then there's 99% "anhydrous" alcohol that has zero water content if you really wanna go hog wild. You don't need that, however, just to clean CPU heatsinks. It's more suited for exposure lamps in copy machines and other applications where zero residue is more important.

FYI, you can typically find 91% alcohol at Target, Walmart, Walgreens and other pharmacies. And it's pretty inexpensive (usually less than a dollar a bottle). It's not hard to find, in other words.

Nail polish remover works, it's mostly acetone.

Acetone works, but it will desolve most plastics, so methanol is safer.

well, i've got a problem.

I cleaned it off, and put a small line down the middle like artics website describes. I did my first boot into the bios and it's showing a temp of 70 C.

What gives? Do I need more compound, or maybe the heatsink isn't contacting well? I did have issues installing the heat sink, those little plastic pegs don't seem to really work right. It *seemed* like it was installed right though.

70 C is crazy high right?

Yes, it's about 30C too high, for idle temp. You removed the motherboard from the case, before installing the heatsink, right? And all four posts were completely seated, as far down as they would go? It sounds to me like your heatsink isn't contacting your cpu very well at all.

grr, i'm next to sure that's what it is.... because no, after I cleaned it i put it in while the MB was installed.

Also, I forgot to mention. My mobo has plugs for a system and power fan, but as far as I know nothing I have plugs into them. I have a p180 case and gigabyte ds3. I have plugged in the cpu fan, and my bios reports on it.

I took it back apart to make sure it was secure. It's definitly as secure as it'll get, but those little pegs just don't seem to be working just right to me. They just seem to flimsy or something, but it doesn't wiggle in any case.

I kept the case open to watch the fans, and it looks like the cpu fan isn't working. It should be going at all times, even if it's slow right? Cause it kinda jumps, then stops, then jump starts again and stops over and over. This clearly would make it run hot, but why isn't it working? I've got it connected, and the bios reports on it.

 

[Darrvid]

Never mind that last edit. I'm watching it in the bios. Temp is now a cool 25 C which is when the fan starts to kick in. I still can't say I'm at all impressed with the stock heatsink installation, but whatever, as long as its working.

 

[graysky]

Have you tried plugging the cpu fan into your powersupply directly or disabling the managed fan option in the bios so that it simply runs 100 % of the time? I have never been a fan of "managed fans."

What are you hardware specs besides the DS3 and p180 (cpu=?, hs=? fan=?, etc.)?
Did you use the thin line method when you applied your AS5?
What are you current idle/load temps and are you reporting tcase or tjunction temps? Not sure, read this thread.

I don't know what is up with all these instructions saying to use a line, a glob, or whatever. I just use a clean zip loc bag to spread a thin layer on both the heatsink and the CPU. That way you get complete contact, not just good enough contact. The thinner the better.

I use the line method, and it works great for me. I think the stock intel cooler would be noticably more effective if the circular copper core actually covered the WHOLE IHS, not just MOST of it.
