Sad thought that that hyper 212 is gonna loose its sheen ... I love fresh copper...

Useless thought --- that Ram cooler, A. is not needed; B. Is gonna cause more turbulence..

I'm off to play cs 1.6

GhostBusters is a blast! Only thing I dont like about it, is it's far too short.

Having gone over several forums and reviews ESP at Toms and guru3d , I was shocked to check out the temps on my (custom) MSI 6850 OC -- these were spps'd 2 b cool cards ....

And as I have seen other people comment on the same --- one general concusion and this thought is shared by many.. The first batch of these cards were well polished and we're getting sub standard builds== leadin to high temps.. Think about it.. I was getting a delta of 22C over what Tom's gave for loaded temps in furmark-- I used occt.. not much to pick from.. and a reseating of the same card w/ fresh TIM gave me a drop of abt ~ 12 C ..

So.. at overclocked 940/1201 @ 1.231 V .. I get 3958 P in 3dmark11 when It should be > 4K.. shame... The HOT vrms must be jumpy.. or the card is simply downclocking.. as these cards are designed to on stress... Nothing conclusive from me.. but hate to MSI >:@
first I have to agree the vrm cooling on this card is bad .but my core temps are fine the gpu cooling on these cards is great.That said if your vrm temps are high its more than just cooling.I have 2 of these cards and only one has this issue. the problem is the card with the hot vrms is pulling more current and at load is making your card hotter.

changed the tim to shin-etsu(helped the core temps)
modded the plastic case so the fan sticks out a little more(helped core temps)
tried 2 different pads on the vrms(no change 20c difference from card to card at100% load)
after changing the pads im pretty sure the problem is bigger than cooling.If there was nothing there and you added a heatsinc you might get 10-15c at most but replacing the heat sinc is not going to give you 20c.

And your cards are not downclocking you would know.when they downclock it goes back to stock or worse performance.

@0razor1 Thanks for the recommendations. Will replace the TIM, but I definitely have to get a new CPU first. Think a Phenom II x4 970 should be good enough for now until the bulldozer arrives.

@Doolie Won't post any scores cause I got a lot worse score than you. 6,500ish. I know the CPU is bottlenecking but there must be something else going on.

1. Doesn't this simply compound the heat ??? Bad, bad vrms..
2. I used CM's Thermal Fusion 400-- neat stuff.. Dropped 15C on the core.
3. Thermal pads on the VRM ?? My VRMs have no cooling :/ Should thermal pads suffice or am I bordering stupid here??
4. K. They're not downclocking, but are definitely underperforming.
5. Raising the fan w/ a couple of washers helps temps?? I thought that only serves to reduce noise. Tell me !! Shall get to it at once ! Our coolers are similar !!
6. I am pretty keen on soldering extra fins to my current fins w/ mayB an extra fan -- ntn concrete planned but must as the summers approach.
6b. Could simply slap on my accelero s1 ?? BUT THOSE VRMs will BURN . I'M SURE :!

My card :

Well , I for one have a 955 ( swapped it w/ a friend for a beer as I had a PH 2 555 unlocked to 4 cores at 3.2GHz @ 1.38V but I wanted to go higher...
If ur into this .. it's a stupid wall one hits at abt 3.8 GHz even If I go from 1.4V (3.8GHz stable) to 1.5V (3.9GHz), Its stable, but the comp will ALWAYS shut down and reboot w/o a blue screen-- no sound jitter either.. so Don't buy a 970.. Doesn't justify the premium.. Get a 955 and U're good to go. Oc it to 3.8 and more If u're lucky but GET an aftermarket cooler.. I have the CM hyper 212+ --- cheap and efficient-- cause of the HDT heatpipes-- just like ur gfx card

I can get a 955 for about 150€, 970 is at 180€. The hyper 212+ is 25 bucks. Think I paid a lot more for the AC Freezer 64 pro. Does its job rather well. 26C idle and 46C full load. Running at 3.9GHz atm. Stable at 4GHz but stabler now.
Got a tube of ZM-STG2 TIM.. Good enough or do I need better?

I'd recommend keeping ur current fan from the asus and tie-ing them on !! Use a couple of zip ties and you're good to go.. unless you simply mod ur cage!! What about that ? That's what I did w/ my palit, and the fact that ur using the stock fan , EVEN AT 100% makes as little noise as if it were at 20% --- simply cause of the lack of turbulence!! --- Or a Slipstream ?? Bend the fins out a bit and u cld slip one of them in

This going to be an HTPC (kickass) or what

EDIT : just had a look at ur case again , the second pic, and u can bend the accelero around that cage !!!
Very important--- find something to cool those vrms man they're gonna bake.. ESP w/ a good fan in place. and a good fan can only do so much..
Y not just WC the whole thing...

I hate the noise of this thing I'm not kidding you. I think the fan might be a bit knackered, I will defiantly try out this little raiser thing you are talking about on the fan to quieten it down.

Waiting for my VRM sinks to arrive in the post!

So you think the accelero s1 will fit then? If I have to I will zip tie a fan to the outside grill of the case.

I might stick some AS5 thermal paste on too.

1. These fans are awesum,, its the turbulence and the pressure (static) that makes noise...
2. Raiser thing is something I read about maybe a page back.. Supposedly lowered temps but if i can think straight right now ( beer, beer , loads of beer) then should lower noise too (obvious conclusion) but not by much.
3. Yes, am SURE the s1 will fit, maybe with a bit of bendin, even around that steel bar u have going
4. WHY tie a fan outside your beautiful case??
5. Stay AWAY from the AS5 for the s1... ITS CONDUCTIVE, U'll blow something )))) And hence I stick with my coolermaster --- try zalman/ AS ceramique/ as mx-4 ---- mx-4 the best IMO.

Yeah, sounds good. Has good thermal conductivity but sad density ( they call it specific gravity.. my my --- look for AS mx-4 if you can -- the best w/o conductance :__D

955 it is!!! win win win!

I was on a budget, and despite a rough base, HDT is FAB and so the 212+ did it for me.. My rig is a year a few months old and now I'm throwing in an SSD -- vertex2 60E as a boot drive.. WOO hoOO!
