Quickly after installing my K6 system I realised how noisy all the fans were back then…the stock CPU cooler just runs a small fan at full speed regardless of the CPU’s generated heat and I wanted to throw the whole system out of the window after 30 minutes.
So I began searching a good and quiet cooler for the K6 box…as nobody is selling Socket 7 coolers nowadays it wasn’t easy at first. Then I remembered that the Socket 7, 370 and A actually had the same fixations and it turns out Arctic Cooling is still selling a very nice cooler for them!
So I bought a couple of Arctic Cooling Copper Silent 3 (also known as Copper Lite) for Socket 370/A. I doubt they will continue selling them for much longer so grab one if you can…as you can see on the picture above it’s a massive cooler with a copper core. In the package there is also a tube of thermal paste which is nice.
On the GA-5AX you’ll have to cut away an unused part of the fixing system because there are capacitors on the way…not a big issue.
The biggest issue you’ll have with such a large cooler are the capacitors on the side of the Socket. In the picture above with the 12.5mm tall capacitors I replaced it works just fine, but with the stock 15mm capacitors found on the GA-5AX it will not fit unless you work with your Dremel.
The fixing mechanism has to be installed this way, with the pression point at the center of the CPU. I found that the best way to mount the cooler is to remove the screw, gently put the cooler into place while the mounting pins are lose and then apply a moderate pressure with the screw.
As you can see the final result is quite massive but also very quiet and the K6 runs at a completely cool temperature…no wonder there as it was designed for the very hot Athlons at the time. On the package it’s even written “Cooling Capacity: 90W” so don’t worry too much about cooling a K6 😉
