Computer Cooling Mysteries

I’m not into the whole overclocking thing. It’s not that I’m not technically inclined, it’s just that overclocking is increasingly becoming pointless, with overclocking being done purely for overclocking’s sake and too many people viewing their heavily-cooled, frequently unstable computers as metallic surrogates for their own shrivelled penises.

That aside, I do like a quiet computer, so I have exerted the odd bit of time and effort on fans and heatsinks and things.

Until a month ago, I was using a 1GHz Celeron with 384MB of RAM. I recently got ahold of an Athlon XP 2400+, which is AMD’s rather retardedly confusing designation for a 2GHz processor.

With stock heatsink and a tolerable mid-70s room temperature, the Celeron ran around 105 degrees Fahrenheit, and my Nvidia GeForce something-or-other video card ran at around the same temperature. Not bad at all, really.

With stock heatsink, the XP 2400+ ran at 125F idle, getting up to 135F after heavy use. Still (just) within specs, but not encouraging… in fact, the heat from the CPU and the Northbridge and it’s dinky passive heatsink were heating my poor video card in the AGP slot to 120F. Oy…

Well, I changed the passive Northbridge heatsink for a neat little heatsink-plus-fan combo, that runs at around 20db, i.e. virtually silent. CPU temp dropped five degrees, as did the video card. 130F is still pretty hot, though…

So I replaced the stock AMD cooler (thereby voiding the CPU warranty, incidentally) with some big huge monstrosity that glows bright blue… while much quieter, it only dropped the CPU temp anonther 5 degrees fahrenheit, and didn’t do diddly-squat for the video card’s temp… not that I was really expecting it to.

That was two weeks ago.

Today, I happened to glance at the temperature monitor… and the CPU is running, at nearly full duty-cycle, at 99F.

My only explanation is that the silicone grease between the CPU and (copper-cored, natch) heatsink takes some time to cure or harden or have something happen to it in order to do it’s job properly. This being the first new computer (or at least new CPU) I’ve ever used, I was evidently unaware of this phenomenon. Of course, I would seem to have spent $15 on a new heatsink and fan I didn’t really need, so this new tidbit of knowledge is not without price, literally or figuratively.

Go figure…

Silly ICQ Scripts…

Mark’s blog has some entertaining fun with script-bots on, I assume, ICQ. I have to wonder whether these things are hackable… are there secret commands they can be given? Not a deep thought, I admit, but, hey, I’m sure someone else has thought of it…
