Q6600 weird temps skyrocket

[Rainmaker]

Is this issue specific to all CPUs or just the quads/Q6600 I'm upgrading in the next week or so and this thread's got me worried.

Well, my personal experience with them so far has been pretty poor, as I'm 0 for 2 in terms of Q6600s that actually work, but a lot of my friends have them and think they're great, so don't let my troubles colour your perception too greatly.

Hi mate, you bought a really cheap and under-powered heatsink to go with your Quad-Core. You may have save a few £££ but look at all the agro and headscratching its caused you!

I had a nightmare using that heatsink with just a Conroe dual core!

It seems some of the ACF7Pro's are of a lesser quality than others. I have always said that heatsink is a POS and I always get several people popping up stating it's the bees knees! Those same people normally had a case like the Antec 900 with all the fans set at full whack!

Get yourself a better heatsink and you may find your overheating troubles go away!

Yup AF7 is only a touch better than the stock heatsink when used on a Q6600

Did you read the part where the last Q6600 I had in exactly the same rig idled at 17°C less than the current one?

Unless you're saying that's the 7 Pro's fault I don't see what point you're trying to make.

edit: sorry for being a bit acid again but come on, Q6600 #1 idles at 33°C, Q6600 #2 idles at 50°C, how do you reach the conclusion that the cause of this is LOLOL CHEAP HEATSINK

***ATTENTION MURDEROUS G***

1. The heatsink isn't that good to start with.

2. Don't make an assumption that all CPUs are or will be the same.

3. Your first Q6600 may have had a flat base, that made very good contact with your heatsink, resulting in cool temperatures.

4. Your new Q6600 may have a slightly concave or convex base, therefore it won't be making good contact with the heatsink, resulting in poor heat dissipation and causing high temperatures.

**5.** Listen to the advice people are giving you, as this has been said many times, yet you seem to think if your first Q6600 was cool, then all others must be!

1. The heatsink isn't that good to start with.

Should be more than enough to keep a Q6600 below 50C at stock.

2. Don't make an assumption that all CPUs are or will be the same.

I never did. In fact I acknowledged this very point in the first post of the thread, if you take a closer look.

3. Your first Q6600 may have a flat base, that made very good contact with your heatsink, resulting in cool temperatures.
4. Your new Q6600 may have a slightly concave or convex base, therefore it won't be making good contact with the heatsink, resulting in poor heat dissipation and causing high temperatures.

Both these points have already been addressed.

yet you seem to think if first Q6600 was cool, then all others must be!

Oh please. This is nonsense. I've said (many times I think!) that I am well aware that natural temps vary from CPU to CPU, so you've just made this up. That aside, I think everyone can agree 50C idle / >70C under load at stock speed and volts is ridiculous, surely you aren't taking issue with that?

Did you read the part where the last Q6600 I had in exactly the same rig idled at 17°C less than the current one? - Only the CPU has changed?

Enough said - If what you have said is true and only the CPU has changed, then clearly the IHS isn't flat. This is causing poor contact between CPU and the heatsink, leading to higher temps.

 

[Happy]

Another factor to consider, is the contact made between the cores and the underside of the IHS, as my Q6600 had a 9-14C core temperature difference until it was lapped, now down to 6-8C difference after being lapped.

answer is either:

a) IHS is not flat.. would take out the CPU get a razor blade and have a check

or

b) and this will really be an arse you have poor contact between the CPU Cores and the IHS in which case there is nothing that can be done..

only other questions I would ask...

1. Have you updated the BIOS at all?
2. Sorry I have only breifly read the thread so if this has been asked before... I take it you have tried re-seated the heatsink?
3. Have you applied the AS correctly? are you using AS or have you changed thermal pastes?

I don't have a razor blade to hand, but I'll check as soon as I get a hold of something suitable.

Ugh ;-( If this is true I guess I could RMA it again. After all, it's exceeding the recommended safe maximum temperature under load right now at stock settings, I should think that's reasonable grounds for return.

1. Yes, to ver. F11 I think, the most recent
2. Heh, about a hundred times now. I've also tried other heatsinks, same deal with them
3. Yes, I think so. I've both manually spread a half-grain-of-rice-size amount, and also tried putting considerably more on, not spreading it, and just sitting the HSF down on top of it, as detailed in a .pdf someone kindly linked for me. I'm using Arctic MX-2.

Hey, I had similar problems with my Q6600 (stock settings). I know my IHS is not flat because i've always had a 5°C difference in core temp. I tried swamping the thing in paste, and the ultra thin layers and the blob and twist technique (properly cleaned in-between each one) but my idle was always around 50°C (ambient 20°C) and under load it got to about 65°C. I'm using a Akasa AK-965 and arcticsilver5 for cooling so wasn't expecting anything too low but thought that was a bit high. Anyway thought I would try one last re-seat and if that didn't work I would give up and just let it run at whatever temp it wanted. I found this guide on the Arcticsilver website

http://www.arcticsilver.com/pdf/appinstruct/as5/ins_as5_intel_quad_wcap.pdf

After trying this it looked like the same thing. But after a few days (bedding in period) i was just keeping an eye on the temp and it has dropped. I now idle at 40°C with the fan turning at only 600rpm under load it reached 55°C (100% use of all cores & GPU for 5 hours fan only went up to 900rpm) That layout for the paste defiantly worked for me!

I know its a bit late, but for anyone else searching on the same problem...
