Thanks mate. I tried :)

I was looking at these fans, but never got round to it.
They're much better looking than the Scythe's and obviously go nicely with a black and white scheme. Only a little slower.

I think the GT's look sexy. I think i might be a GT fan boy though so i don't even need to advise you what i think. ;)
 
Not the GT's you silly boy! The Kama's. 92mm.

I reckon 92mm works a fair bit better when tied to the heatsink vs 120mm mounted underneath with the bracket btw. Past tests back this up.

Haven't tried the GT's, but they should do ok. Shame you can't buy the 92mm GT's any more.

Edit: I dunno. This is all getting very confusing...
 
HI mr Ltmatt i think we have the same card msi7970 oc, I've fitted my Accelero Xtreme and i'm really happy with the quietness.The core stays coolish in gaming (crysis3&tomb raider) 55 ish (1175 core/1575mem/1225 vcore) But as we seem to be focusing now on vrm temps mine are going to 82 on 1 & 79 on 2 this seems high to what you and others are getting would you recomend this is ok ?.I fitted the heatsink's as the instructions said and the 2 part glue provided, could the Alpenfohn Peter fit our Accelero's or which cooling did you end up with on the vrm's?

The problem is the G1 two part glue doesn't do a very good job of firmly sticking the accelero heat sinks to the card. Its possible to order some thermal adhesive from arctic's website (http://www.arctic.ac/en/p/accessori...ac/en/p/accessories/587/thermal-adhesive.html) which provides a much better fit and results in dramatically better vrm temps. However its a bit more difficult to get the heat sinks off. It can be done as i did it recently, but it requires elbow grease, a lot of wiggling and patience. It will come off though its not completely permanent. Like petey has said with the peter stuff ( i think its the same as the accelero adhesive) it dries like a rubber sealant. Just remember to only use it on the vrm sections, use thermal tape/G1 for the vram chips as you don't want to pull them off accidentally. When you apply the adhesive, apply a thin line to each heatsink and press down on the vrm firmly for 30 seconds.

I posted a picture here showing the best possible heat sink placement. A few of the sinks in this picture are placed incorrectly but by reading the red writing it should show the best possible placement.

To confirm.

One L shaped heat sink top left on the vrm. One long thin heatsink on the top right vrm, followed by thee L shaped heat sinks below it. If you want to refit the accelero you will need to clean off the g1. Thoroughly clean off the vrms, vram chips and heatsinks using TIM cleaner and a rubber. (a pencil type rubber, not a condom :p)

The large heatsink wouldn't fit under the Accelero. The slim ones on the left would do a good job though.
The paste would be fine.

You could go to Alpenfohn's wbsite and tell them you have a Peter 79xx and ask if they'll send you a replacement tube.
They did for me and I didn't have to provide any proof of purchase.
 
If you want to use the beast-aka big alpenfohn vrm heatsink, you need to dremel the AC heatsink so that it fits:

HI I've sent a ticket of to them(don't mind paying for it if i have to though)
a bit cheeky but worth a try.

it's a shame that wont fit as it gets the best results.
 
Oh it brings back the memories pete, and a tear to the eye too now it's gone.

It was at least a good 25c+ lower in the high 70's when oc'ed, but my vrm temps were considerably higher in comparison in the first place as I was running CrossFire-they run hotter than when in single card mode.

I was too lazy to take the other one out and test it on it's own though.

Pete after checking your fitting post, slap me for being stupid, but I take it insulating tape won't shrink/melt with the high temps from the beast?

Dunno. Good question :D
I'll have a look in a bit and see how it is.
I doubt it's got hot enough to harm it tbh. /smug mode

I didn't even need to put it there in the first place really. Getting it off would be a major PITA as you can imagine...

Are you mad?

It's not work, it's fun I tell you, gets the pulse going well fast too after you clean it up, assemble it and hope you didn't miss a metal shaving as you press the power button on!:eek: :D

Nothing like a bit of DIY.

Then again, there are some people here who think putting a PC together is a stress filled, major hassle.
Those guys baffle me...

Cheeky and worthwhile :)
Just hope that it doesn't arrive solidified like my first replacement.

Today i have woken up with the urge to buy my own beast and stick two 1850GT fans on there. I'm hoping it passes and normal service will be resumed shortly. Damn pete for teasing me with those vrm temps.
