Gibbo you need to get a massive load of these in..

Custom loop with a good block like ek will wipe the floor with one of these, a good loop on a 7970 would give you high volt/clock temps in the low to mid 40's.

My 7950 running 1.25v and 1150Mhz hit mid to high 40's on an Antec Kuhler 620 using the bracket mod.

This Arctic cooler has the same pump and radiator.

I abselutely loooooooooove something like a corsair H80i or 100i but for GPUs instead and at around the same price point. It would be perfect for a lot of us who just want to cool the core chip(with heatsinks ofcourse on the ram and vrms and whatnot) I would buy one in an instant if i know it would fit in the first place.

He didn't find any that support 7970/50's though, which is what i was talking about.

the 7970 version doesnt work on a 290 anyway as you dont need the shim. the gpu is in a different orientation to the 290 so it is largely irrelevant.

i will still test the cooler on a 290 to see if it works.

I don't see anywhere support for the 7970/50 so i was correct.

you dont need the shim. the 7970 version is not compatible with a 290.

LtMatt said:
Yep thats what i said from the start. However the shim won't be needed for the 290X as the core is flat so just need to wait till he can test to see if it fits.

Looking forward to see if it fits. The only downside of the Accelero Hybrid when i used it on my 7970 was the rather lacklustre vrm cooling. The core cooling was fine and kept my 7970 below 65c at 1.225v @1250/1823. Unfortunately i found myself limited by the rocketing vrm temps which were up at 80-100c and this did cause some stability problems in some games.

Boom... I ordering 2.... Have OCUK just got these in because of this thread?

hang fire, we dont know if they work yet.

I did get them in because of the thread yes.

tbh for the price, i would still take a MK26

See matts comments further above about vrms, this is the main reason I'm not a big fan of this type of gpu cooling, no amount of small heatsinks and fans are going to come close to a bit of copper and a direct water path. Even some 'full cover' waterblocks suffer this fate I.e. alphacool & early xspc as they don't have active cooling on vrm areas

Hot vrms are inefficient, so core temps are only a part of the picture as ideally you want vrm temps as close to the core temp as possible, in your situation I'd wager the vrms are running a good 35-55c hotter then the core.

Its not to say these hybrid aio cooling solutions aren't any good, they can fair quite well as the ares did, but asus dealt with the other important parts well in the cooler design.

My VRM's on my Twin Frozr 3 7950 were fine...

They don't worth with what?

Is there an ETA on them?

While I very much agree with you, it is possible to get reasonably close

Yes but you had more fans than Justin Bieber Pete.

Uncle Petey · 25 Oct 2013 at 15:30

Justin Bieber has only 3 fans?

Besides, pgi said "no amount of small heatsinks and fans are going to come close", so my OTT efforts are reasonably relevant even if nobody else is likely to go that nuts

Was that with the stock fans at 100%. What was is like when set to 50% ? Is is reasonably quiet? Do you think this is feasible with a 290 or 290x ? The mounting holes look the same, and I hear it should need no shim.

+1 VRM temps were the reason I ditched my 7970 Accelero. The core was sitting at ~60c and the VRM's were sitting mid 90's and often approaching 100c :O

Now I've got my core and VRM's sitting ~40c under a big slab of copper

90-100c is very extreme and is just down to poor cooling, even my Twin Frozr 3 7950's VRM's don't hit any where near that with the stock cooling.

almighty15 · 28 Oct 2013 at 09:01

Just paid for mine so when they get here in the next few days I'll do a mini review on my 7950's so people can see what these can do

K1LaW8tt5 · 28 Oct 2013 at 10:40

Interested to see if they fit on the 290x , i dont have the space for the mk26 and not enough money to setup a loop lol
