[dba-Tech] How to revive an XP POS PC

I have a Corsair water cooling unit in my PC, I only got it because I failed to notice that the processor I'd ordered didn't come with a heat sink & fan, so I had to go out and buy something if I wanted to use it that day... Happened that the only thing they had was a water cooling system. I'd always been dubious about introducing water to my computers, but as it's covered by the house insurance, I figured I should try everything once :-)

I know the computer is quieter than my previous one, but that could be due to a better design (in terms of air-flow), the newer components are more efficient and don't heat up so much, and they're not old and full of dust. It's hard to compare a new system with a 7 year old one, and make any decent conclusions in that way, but it's definitely quieter and faster, and that's all that really matters to me.

Hello Jim,

Have you built any water cooled units yourself?  Can you tell us what units you have used?

First comment I have to make is if the processor is sitting quietly at 38 -
40 degrees Celsius, why would anyone need to make it cooler.  They will happily work at even 80 degrees C, so when it is below 40, absolutely no need for water.

I did some experimentation with them a few years ago.  I built a machine with a cheap €15 - €18 passive heatsink with a fan and compared various tests.
I then did more tests with a high quality passive cooler and fan (approx
€25 - €28).  It was one or two degrees cooler after running for a few hours.  I also tested with Prime 95 and the passive cooling was ok.
Finally I installed an expensive water cooler and ran that for over a year.

Result:  1) Not any cooler at all 2) You can hear the pump running if you listen carefully.  It is not silent.  3) Once the radiator became dusty, the air blowing through it started to whistle slightly because the opening were slightly more narrow.

In summary, I saw no benefit what so ever with water cooling.

Nowadays, I just use a simple passive air cooler with a fan.  Total kit costing €15 - €18.  For my own machine I usually disconnect the CPU fan and convection alone takes of dissipating the heat from the CPU.  When I do that, my PC has no moving parts at all.
