Well good news lads the gpu turned on ok.

I won't lie my heart was in my mouth. Now to see if its made a difference.

Had it hanging on the PCB for about 30 minus and the tape held, over time it probably would, but without vrm readouts on the DD, I was glad it was a tight fit, good peace of mind that it's not going anywhere pete.

Yeah, I hear that.
Have to say though, I've had it attached to my old card for the last few days and the card's been manhandled, the cooler's been on and off etc and it's still exactly as it was when I put it on.
Of course, it's not as solid as glue and I'd probably find myself constantly checking temps to make sure it's ok

If I couldn't read VRM temps, I'd want some extra security too

Anyway, I'll let you know how it performs in the field whenever my new card turns up.

EDIT:
Matt, that looks like you may have actually improved airflow to them. Maybe.

Idle temps, here comes the moment of truth.

Not the only one.

Remember and let your ambient temps build up in the case for a better comparison with your other data since your rig is running from cold.

Uplay updated and now farcry 3 crashes as soon as i try to load it. That was the only thing i could compare my temps to for now Lol. Typical.

Not got any old results for Heaven/Sleeping dogs etc?

I don't have that installed any more.

However i found this post here http://forums.overclockers.co.uk/showpost.php?p=23767974&postcount=380 and i have that installed so will run it now and see how it compares.

Uncle Petey · 1 Mar 2013 at 14:30

lol Tommy. That's probably not the result he'd like to be remembered for

LtMatt · 1 Mar 2013 at 14:34

Here are the results.

Using G1 + AC Sinks

Using the Copper Sinks +L Shaped AC Sink on VRm left

VRM seems identical. Everything else is better. I think i might improve vrm if i put a whole line of akasa tape over the vrms instead of those little squares. Also one of the vrm sinks didn't stick very well and fell off a few times but its on at the moment. Might take it apart and use akasa tape.

Uncle Petey · 1 Mar 2013 at 14:43

The L shaped VRM2 sink seems to be better than the old one at least.

LtMatt · 1 Mar 2013 at 14:47

One thing i have noticed. I can clock higher before i get artifacts, not sure why that is. Really temped to take it apart and try the akasa tape.

Uncle Petey · 1 Mar 2013 at 14:49

Worth a bash I s'pose, but I wouldn't expect much difference unless the adhesive is notably poor on the Enzo's.
Are you thinking that it may help if the gaps between the VRM's are covered?

Pmsl pete, and then matt takes it apart again...

Uncle Petey · 1 Mar 2013 at 15:39

Heh, you'll be seeing the same from me whenever I get my card

LtMatt · 1 Mar 2013 at 16:40

I tried the long strip method but its not as effective as i hoped. Plus its hard to ensure you're placing the sink exactly on the vrm. So i ended up scrapping that half way through. This time i carefully cut out squares, some slightly larger some slightly smaller for the vrm's and placed all the sinks on there. Knocked 1c off the temps. The akasa tape is really good, its won me over. Who needs G1.

Uncle Petey · 1 Mar 2013 at 16:51

I wondered what took you so long

Like I said mate, if that tape can hold the monster Alpenfohn sink...

Btw, is your new lower core temp due to Gelid GC and are you happy now?

I'm happy.

Core temps are lower, yes probably because of Gelid. I think the L shaped sink has made a big difference. I'm seeing much less artifacts when overclocked heavily and vrm temps rise. I would definitely recommend copying my setup and using those cooper heatsinks on the vrms and putting a chunky sink on the left vrm.

Gonna re-download farcry 3 now.
