Aside from the moving it after you've put it on bit, I think that's the way a lot of people do it.

If that were the case I'd expect the temps to be higher. Then again, assuming there's not some sort of problem with fan speed reporting on his system [either software or hardware] his fan [same as I have] is running twice the speed of mine.

The 1 I really hated was that pink stuff you'd get on the bottom of Cooler Master heatsinks. IIRC the stock heatsink that came with my XP1900 had the same stuff on it. Simplest way to get that stuff off was to remove any plastic parts [including fan] from the heatsink & then put it in the freezer for a couple of hours until the pink stuff went brittle, which made it easy to scrape off with a finger nail.

Yeah, but those C2DQs are 65nm, aren't they? As for the 125w of mine, there's an AMD util that's supposed to monitor power useage. Hopefully it'll give more than voltage, which I already know [1.43v - Web_junkie: yours shouldn't be higher than 1.35v (+/- 0.05v)].

Actually, there are 65w in 90nm as well:
http://www.amdcompare.com/us-en/desktop/default.aspx
Set options as follows:
CPU: Athlon 64 X2 dual core
Manufacturing Tech: 90nm SOI
Wattage: 65w
& you'll see there's models listed from 3800 to 5200

After a bit of searching, there are 4200, 4600, 5200 models available at 90nm & 65w.

65nm: plenty of 4000+, 4400+, 4800+, 5000+

Where?

It was the T-bird [specifically the 1.44Ghz model] that was legendary for its heat output, not so much the T-breds.

Won't be using the puter much today so no point worrying about the high temps, AF will be here tomorrow hopefully so it won't matter, unless it's a faulty board as Zing says, will find out soon enough!

Hmm... I had a thought about that. AMD provide some utils here that might be useful. I was thinking mainly of the power monitor. It would be interesting to see if they tally with SpeedFan & PC Probe. If it's using too much power that could potentially cause an increase in temps [would mean Zing was right about the mobo ].

That's what I do as well.

40°C? [img]Download Failed (1)[/img] That's bloody warm for the inside of a case. Either the reading's wrong or... I dunno. From what you've described you ought to have plenty of airflow to keep system temps lower than that. What about the Crosshair's extra plug-in temp sensors, maybe you could use them to find out what area is putting out the extra heat. That might provide the clue as to how to drop your temps. 60°C [under load] may be uncommon for a CPU, but so is 40°C for a system temp unless you lived somewhere really hot & didn't have air conditioning.
