AMD A64 Heatsink roundup Q2 2005

Cooling/CPU Cooling by jmke @ 2005-05-15

In this massive Athlon 64 heatsink roundup we compare 17 cooling solutions from different manufactures including Scythe, TTIC, Arctic Cooling, Thermaltake, Titan, Thermalright, Zalman and Coolermaster.

Thermalright XP-90C

Thermalright XP-90C:
Supplied by: Thermalright XP-90c

When Thermalright released their XP-90 a lot of people where wondering what its performance would be, if Thermalright made it out of copper. Well today we have a copper version of the popular XP-90 (~$40), aptly named XP-90C (~$50). Costing quite a bit more then the vanilla XP-90, let’s see how it performs.

Specifications :

Compatibility:

Intel: Socket 478/775

AMD: AthlonXP/64/64+ Socket754/940/939

Heatsink Dimensions: 116x96x75mm
Weight (without fan): 690gram

In the Box :

A short but descriptive manual is included, mounting gear for Intel and AMD, thermal paste and a Thermalright sticker.

Construction :

Construction is identical to the XP-90, four heat pipes are joined at the base (which is very smooth) and they transfer heat to the copper fins at the top.

Installation :

After installing the custom mounting bracket you simply clip the XP-90C in its place, installation does not take more then 5 minutes.

Performance and Noise :

As we were able to mount the Vantec Tornado onto this heatsink, it’s no surprise that performance goes through the roof. But even with the more modest Panaflo and Papst fans performance is very good!

The real question of course is whether or not the Copper XP-90 is any different from it’s aluminum brothers, here’s a comparison with the XP-90 and XP-120

As you can see, with high speed fans the XP-90C offers only a small improvement over the XP-90, however when we use slower fans like the Panaflo and Papst the difference becomes bigger. To sum it up:

Difference: XP-90 vs XP-90C

High Speed: ~2°C

Medium Speed: ~3°C

Slow Speed: ~4°C
