I do, but that's mostly to make it easy to perform full backups. The machine run coolers, though it spews more RF, which keeps atomic clocks in the same room from synching.
By the way, check the CPU cooler occasionally. Mine hadn't been cleaned since I bought the computer over eight years ago, and you cannot believe how clogged with shmutz the heat sink was.
Not a problem for me.
I clean them moderately regularly. Plus I don't operate in a very dusty environment.

Nor do I. This wasn't dust -- it was more like gobs of sub-microscopic carbon particles.
Never seen that. On the CPU cooler itself you mean ?
Grham
Really? ;-)
Of course many, if not most, portable multimeters have type K thermocouple inputs (of dubious accuracy, but good enough for this sort of thing) and many are supplied with a bead thermocouple.
Less than 12 weeks? You have a bright potential future with Samsung, HP etc.
Funnily enough, often some of the cheapest ones have the thermocouple input but I used to keep a supply of type-K themocoouples anyway. I like keeping an eye on temps.

On the heat-sink. It reminded me of the black stuff that comes off a CRT faceplate. Only a lot more.

I buy the replacement parts at a Hollywood dub house. Last year I bought 14.000 'lytics , 10,000 installed by 3 of us. My first choice in Panasonic FM but the selection isn't as wide as the second choice of FC caps. If I run into a physical size problem Nichicon PW series often helps. For surface mount first choice is Panasonic FK and sometimes HC series. If you're doing this a lot like we are, Metcal soldering irons are HIGHLY recommended. The STTC-126 tip (700 F 30 degree bent tip) is really good for clearing stubborn holes - usually ground planes with lousy thermal reliefs. A lifted pad is a very rare event with a good soldering iron.
100uf 25V (most common value for us) cost 20 cents in 1's 10.28 / 100 but are only $57.54 / 1000. I try for 1000s whenever possible.G=B2
I've seen that in downtown areas where a lot of Diesel trucks go. I assumed it was particulate from the exhaust.
That could be it. Roll on clean diesel technology.

Thankfully I have no atomic clocks to worry about.
Yes, I keep an eye on that kind of thing.

I would imagine that it was a crappy capacitor, perhaps one of those knock-off Taiwan caps. Sceptre LCD monitors had a rash of crappy electrolytics which they used on the outputs of their switchers a few years ago. Many computer motherboards also used icky caps. The two Sceptre monitors that a friend had crapped out around the same time. I replaced the high stress caps with United Chemicon caps.
For my pulse power amplifier applications, I stick to United Chemicon.
Which series do you use? U-C make several qualities in radial lead cans.
This box is a dual Xeon, with huge CPU heatsinks that get very filthy. I take the fans off & brush out the heatsinks once or twice a year.

The ethernet tokens should also be polished every three weeks.
