Need aftermarket cooler advice for my Sapphire 7950 OC

Hi.
Need tip to what aftermarket cooler i should buy for my sapphire 7950.
Was mocking about around my rigs today and managed to push a wire into on of the gpus. resulting in fan blades shattering…

I was considering the Arctic Accelero Twin Turbo II, buut it doesnt seem to support the 7950, neither does the Extreme version???

I have that cooler running on my 6970, card is running 100% with 40% fan speed on 37c :D

It seems they don’t support 7950 indeed :(

look in the support theres a part about 7970/7950.
seems that it works if the card is newer than february 2013.
Which means i gotta take it apart to find out…

I have 4 sapphire reference 7950s with arctic accelero extreme 3 aftermarket coolers. To be honest I dont like the design that much. They are very quiet coolers and keep the core in the low 60s but I have to keep the fans turned around 70-80% (and this is with a big 24inch fan blowing on them) or something overheats. I think its the VRMs. The design has a critical flaw that makes it bad for rigs. Most cards blow heat out the front or back but these shunt all the heat over the top and right into the fans of the card next to it. Its really bad when you have 4 of these lined up. They just pass the heat down the line, amplifying it until the last card overheats. You have to have a big jumbo fan moving air between them to make sure that heat doesnt get passed between the cards.

Here is a picture of the vent on top of the card. Its a slightly different model but still same vent.

Had the Accelero Extreme (7970 edition) to for my replacement on the shitty XFX 7970. Worked very well for me (need fan to push air through between the cards).
I do concur with having to have the fan speed on 80+%, and yes its due to the VRM overheating. Since the cooling for those is not connected to the main cooling block in needs air circulation strong enough to blow on the small fin block.

Ill see what happens. all the cards mine fine now (noisy as hell though due to 3/4 fan blades ;D). have two that is going to be taken on warranty (sapphire shitty stock fans don’t last long).
If i get the same replacement as last (280X), i will be very happy and just sell the rest with accelero turbo II fans=)
