Installing AXP-II on an PC 6950 2GB [56k Warning]

post #1 of 5
Thread Starter 
This is my 3rd fray into 3rd party cooling for my GPU...first and second were with my GT-7600 and my HD-5750 and now my PowerColor HD 6950 reference card.

The main reason for me getting this cooler was because the reference blower was really really loud...and it's summer here in Toronto and my temps won't go below 50*C even with a TIM change. So I decided to take care of my investment and get a 3rd party cooler.

This is my first log on what I did...if there are any errors please do PM me and I will fix the post.

And here it is:



Looking at the inside of the package they've included several aluminum heatsinks for various gpus...but there are some NVIDIA gpus that aren't supported and have to purchase additional heatsinks for the VRMs.



Here's a comparison shot between the reference cooler and the AXP-II.



Looking at the copper base...it isn't machined as well as I wanted it to be...I could lap it but...that won't happen for another year when I change the TIM.



Right now the reference cooler is removed from the gpu...I took this image for my reference as to where I needed to put the aluminum heatsinks...



As per AC's instructions, I took my handy eraser and gently scrubed the top of the parts I needed to put epoxy on, this included the VRMs, RAM and a little VRM (afaik) on the top left...



Moving aside the cooler and the GPU, I started mixing the thermal adhesive...you have 20 minutes of working time with this mixture and it settles in 5 hours.



After coating the VRMs and RAM I proceeded to place the heatsinks...there were no instructions on the manual so I had to eyeball the VRM heatsinks and fit whatever was available.



So far so good, time to clean the GPU chip!



Fits like a glove! (The recommended plastic spacers were 3mm w/c was included with the kit!)



Here's a close-up of the contact between the cooler and the GPU...it might not be clear in this shot but from what I saw...it was spot on...and I didn't need to tighten the retention screws too much.



At last...it's installed and I'm happy.



I ran into a snag while installing the cooler on my CM690II. It wouldn't fit with the main 2 HDD cage. So I did remove the HDD cage w/c was riveted. Took me a hood hour with a dremel cut-off disc and a power drill...it really was a pain to remove but I am happy with the result.

So right now...it's 25*C ambient and what used to be 50*C~55*C @50% fan speed on the GPU is now 35*C~40*C @50%fan speed.

I'm really happy with the results and the temp will really go down come fall and winter.

I hope you guys enjoyed this read as I have enjoyed installing this GPU cooler.

The only lesson to take from this experience is...measure measure measure.

I bid everyone a good day.

Hi CramComplex,
Thank-you for the pics and the explanation - that was great and i think it works great as long as it fits. So the AXP-II would be basically glued onto the graphic card or do you use the screws to install it to the card.......?? My current understanding is that it's like glued to the card....which is the concept that's holding be back with my MSI GTX 560 Ti Hawk....otherwise i would have bought it in a hearbeat to cool my card.

Nice job :-) I've got the Twin Turbo 2 on my 6950. I went with that because its alot smaller yet cools as good and it was only $35 :-)

You screw the AXP on the card not glue it...also you have to use the epoxy provided by AC on the package for the RAM. Also make sure the AXP-II comes with the VRM heat sinks for your card...if not then you'll have to buy them separately.

You also have to research IF you really NEED a 3rd party cooling system. Your stock should be enough for your card. BUT if you have reasons why you NEED it then go ahead...you do risk voiding your warranty.

My main reason for getting this 3rd party cooler is to cool my card w/o having to hear a jet engine every time I turn on my PC and to lower my temps on my OC. (Running at 900/1400 stable 24/7)

Only do this switch IF you really know what you're doing.

I unlocked my 6950 to a 6970 that's why I need the additional cooling of the AXP-II. And besides once the fans die on the stock AXP-II I'll be able to ghetto-rig 3x fans on it! >
