Currently on the stereo system: DJ Shadow - "The Private Press" / King Crimson - "Red".
I've gone ahead and purchased the Vantec VA4-C7040 CPU cooler for my old AMD 1700+.
Pre-Install:
Quaffed a Caffeine drink, broke out the screwdriver set. Ripped open the box and removed the power supply assy.
I must admit that the Vantec has the Cadillac look to it. I've never seen a CPU cooler before it that is visually pleasing.
Three things strike you when looking at the cooler:
- The casing around the fan is rounded, chromed and polished. The fan blades are swept back and put you in mind of the blades inside a jet intake.
- The fins of the heatsink themselves are arranged in a pattern that looks like it's designed to allow the airflow closer to the heatsink core. This is the closest I've seen to "innovation" in fan-based heatsink engineering.
- The base of the heatsink, at the point the heatsink touches the CPU itself is a highly polished disk made out of copper. I think the copper is as common materials go second only to silver in heat conductivity, please correct my if I'm wrong.
Installation:
Applied the thermal grease (included) in small amounts over the CPU core. Proceeded to latch the hefty cooler onto the CPU using the three pronged latch thingy and...
Clang!
Clang??
Clang!
...
...!
Yes, Something-Has-To-Go-Wrong(TM). While I took the precaution of measuring the space available and ensuring that the cooler is of adequate size, it seems that the useless and unused onboard VGA chip has a small heatsink connected onto it. The 3 outermost spokes of the onboard VGA chip's heatsink are in the way.
With sweat running off my brow I slowly and carefully removed those three spokes from the onboard VGA heatsink with a flashlight, a electronics cutter and steady hands. The Clangs of frustration turned into the Clicks of utility and function!
Post-Installation:
Powered up with the case open to see it actually spinning... good. Closed the case and powered up, going immediately to the BIOS PC health monitor to see how the CPU temperature behaves the first few minutes... good.
Booted GNU/Linux and started checking the system... Wonderful.
My old cooler was the AMD supplied original. It idled at about 50 degrees C and went just over 60 degrees C at 99% CPU load (nominal).
The Vantec idles my system at 45 degrees C and goes to about 48 degrees C at 99% CPU load (nominal).
This Gnuplot graph shows the CPU temperature (degrees Celsius) relative to time (every 30 minutes). You can easily recognize the huge dip at the end and arrive get an impression of what I'm talking about.
