Now, that's the max (read: if you reach that, pull the plug!!) temperature supported by the XPs, and I think Intel's are a bit lower (75C). If your cooling fluid is hotter than your CPU, it's not cooling anymore, so you have a big problem (actually, the temperature of the CPU will just raise until either it melts or it's hotter enough than your cooling fluid to create a new thermal equilibrium).

Where the P3 was extremly happy running at the high speed with some very silent fans the XP just wouldn't keep cool even with a much heavier cpu fan and case fans. I also had real stability problems with all 3D games. Temps measured in at 70 celcius.

      This weekend I added a simple water cooling set.

      • A common fountain pump
      • 1 cooling block
      • a reservoir
      • a radiator
      • 1 12cm fan

      Oh and if you use this as a shopping list(don't ask people in the shop or look at plenty of sites) add some spring to keep the tubing from folding up. Anyway it came to about 300 euro's total.

      First I put the radiator inside the case. This cooled the cpu nicely for a while but the water kept getting hotter and hotter. Soon I was back at 70 celcius. I then drilled two big holes and mounted the radiator outside. With a single 12cm softly blowing on it I now have my cpu at 40 degrees after 3 hours of RTCW. Previous five minutes was about max. I am not sure how water cooling could possible make 3D games not crash to the desktop but my problem is solved.

      Next weekend I will add a cooler for my graphics card and chipset and maybe even for the HD, 3 more fans on the radiator should take care of the extra heat and I will have a silent stable cool machine.

      So the answer is why don't I just spend money on a faster chip? The XP 2300 or so isn't available yet and that thing is bound to be even hotter. Yeah I spend the same on the cooling as on the chip itself(pardon me if I got prices slightly off, I make enough money not to really have to take notice) but now the chip finally operates as it should. Of course I could now overclock the 2100 to 2300 and up, but how many more frames do I really need? Basiclly with chips (x86) running hotter and hotter people who want to run their machines without installing a windtunnel to cool it will have to go the watery way.

      The cost is a big one but not more then say a big HD for all you're movies and half of a top vid card. When you have already got the latest cpu, lots of ram, a big HD and the latest vid card a simple water cooling set rounds it of nicely.

      400 watt powersupply is standardish (exacerbated by that freakish AMD's "approved list") and _all_ video cards (reputable ones) have fans. Radeon 9700 Pro has a separate hookup directly to the power supply for more juice. The heatsink/fan included with retail AMD is not usuable and too wimpy (I know at least MSI officially recommends a new heatsink and fan). Some motherboards have fan on their chipsets (MSI KT3 pro or something at least), and a heatsink is standard.
