Maybe you should leave it alone.....
That's what my girlfriend says to me.
Thankfully she's not referring to my Accelero though!

Well, after a quick test, I say get yourself some of this mate: http://www.overclockers.co.uk/showproduct.php?prodid=TH-001-AK&groupid=701&catid=27&subcat=
It held them rock solid
I pulled them off and stuck the massive VRM heatsink to it and have left the card sitting upside down for a bit. So far, it's looking good. Hasn't budged.
My previous attempts with sticky thermal tape were with the thick pad that came with the card. This stuff is thinner and so far, better.
I've actually already got some of that. I'm worried though that it will provide worse temps than the G1. The W/MK of that Akasa stuff is only 0.9.
Well, I'm not even going to try and understand W/MK even after a bit of a google
In my mind, however, I'd say that a thin bit of thermal tape would transfer heat to a heatsink better than a thick pad.
After all, thermal paste works better when spread thinly right? Yeah, it's two different things...
Perhaps someone with a better understanding can help
Basically higher is better.
The reason for my trying a pad is ive seen reports of other people using them on vrm's and reporting better temps. Maybe i should play it safe and stick to G1.
That is a possibility. I think if i want to use the thermal pad though ill have to use a bit of the permanent adhesive. I'm pretty sure that the Akasa tape will provide worse temps though so not sure its even worth trying that.
I could just use the tape instead of the pad i suppose. I could use the permanent adhesive to glue the heatsink to the tape then just stick the tape on the vrm. Good thinking Petey.
I saw a thread from you thinking about buying a 580gtx the other day Petey. Changed your mind again? I thought I'd convinced you to go with a msi 7970.

Petey could you try something for me. Can you try using the glue stuff you have an putting some of that on the heatsink, sticking the heatsink to the akasa tape then sticking the tape to the vrm.
You won't even need the glue if you use the tape.
Oh, and it's better to stick the tape to the VRM's and make sure it's thoroughly on and inbetween the gaps first imo. Then glue the sinks to it if you must.
That 580 was a good price and I thought what the hell seeing as it'd probably do me fine for a little while.
Now, I'm back on the 79xx path again
There's also this, after having just tried the Akasa tape:
No can do I'm afraid. That glue tends to dry up in the tube after a little while, so I have none to work with.
I don't really see the point either tbh. To me, it seems like just adding more obstruction between VRM and heatsink.
What do you think i should do?
What plans have you got for your potential 7970 oc card?
The tape is the easy method Moog. Tommy used tape and its a much quicker install and you can use it straight away. The glue method is the time consuming method.
I think you should wait for the new batch of G1 and then try the Akasa tape before you re-glue stuff.
Buying thick pads and using glue on each side seems a bit much to me. I say use either pads, tape or thermal glue.
Me? I'm going to use the tape to start with. If temps are fine and in line with what I had previously, I'll leave it at that. If not, I'll use the glue again.
I'll still use a bit of thermal paste with a teensy-weensy dab of superglue or Thermal glue for the VRAM sinks.
Failing all that, I may just bung the dual-X cooler on it
What's the dual x cooler?
What thermal paste did you put on the vrms? Do you mean like IC diamond? I have some Gelid Solutions Extreme that i could try. It certainly lowered my cpu temps by a few C over mx-4.
I hope whatever you do you document it well, i know you want to.
Hopefully Tommy will come online soon as we were both looking at this.

Dual-X is the cooler that came with the Sapphire card. It's not amazing, but it's gotta be better than a reference blower.
It's only if I can't be bothered to fit the Peter again, which isn't likely as it's easy.
I didn't use any thermal paste on the VRM's, just thermal glue.
I used thermal paste on the VRAM heatsinks and put a tiny dab of superglue in two corners to secure them.
I'll take plenty of pics for ya.
Was my first adventure not detailed enough?
Ed: That first link looks interesting.
That first adventure was great. That reminds me i never finished reading that. I started it once but even after a few hours reading i still wasn't finished. Will have to go back for a second look. Sent you a trust with details of that thermal pad i just bought. Had a change of heart. I just hope its sticky enough like the akasa stuff.
Oh, don't worry about it. It's mostly out of date anyway with lazy edits providing vague update info.
I'll do a better one soon with less waffle. Well, maybe less waffle. I like waffle.
Well, if all goes swimmingly, it looks like you and me have a cooler war on the cards. (see what I did there? Yeah, I'll get me coat...)
Bring it on! Hopefully my gear should arrive Tuesday or Wednesday.
Schweet. Me too hopefully.
Btw, do you get memory temp readings on this card? It's one I thing I didn't get on my last one.
After sticking on all those heatsinks, you kind of want to know whether it was worth it
You do indeed. The msi 7970 oc card has all the thrills and spills.
Petey get some gelid gc extreme from a well known auction site. Its great paste which ocuk no longer stock any more.
God damn tommy knows his heatsinks. Gonna hit you up on trust petey with some possible alternatives to vrm cooling.
Those enzotech heatsinks look great. Really temped to order the DRAM + VRM versions. Will they fit though.

The moment of truth, or the refit of my accelero as i like to call it, is almost upon us.
With the help of my minions (Tommy+Petey) along with some other dude from another forum i have ordered some of these EnzoTech heatsinks. These will go on the VRM area and should cool much more effectively than the light weight accelero sinks.
Clearance is 14mm according to my calculations and these sinks are 12mm. So yes it will be tighter than a waddling ducks back door, but it should fit.
They even have some high quality adhesive on them so i shouldn't need to worry about using G1 on them. Hopefully all my goodies should be here wednesday at the latest. Expect pictures.

Still fiddling I see Matt.
Hope it goes well.
Just hope I don't see this on Wednesday
If that happens you just won't see me.
Don't do anything silly if it does.
This will be my third time. If something was going to go wrong, it would have by now.
Mine was perfect first time, na na na
I got a dud overclocker though
No it wasn't you said some of the sinks fell off!! Don't worry though, happened to me on my first install. Every time you do it you get better and better and temps drop a few c. Can't wait to get it all taken apart and see how these new sinks affect the temps. I thought i nailed the second install but i had one of the heatsinks around the wrong way. Third time i will nail it.
How can you tell it's a dud?
Also, Matt where did you order those heatsinks? I'm tempted to get some for my first install!
Will drop you a trust if i post the link here the Dons will have my guts for garters.
I could only reach 1250 on the stock cooler and that was hot and in no way stable. The accelero allowed me to reach up to 1325. 1300 stable. I wonder what my card could do in the hands of a water cooling Locky, PGI or Scotty.
We'll never know.
What kinda volts were you using though? That's what I would determine first
I can do around 1300 @1.275v. I'm temp limited at these voltages though. My high asic card means things really get toasty once you start adding a lot of voltage. I will run some thorough tests before i fit these new sinks so we can see how much of a difference it makes.
In other news...
I don't like the colour scheme of your sig.
No shame in it. We are always looking for new recruits.
With accelero you will see temps between 40-60c.
Mod deleted my old one saying it was too big =/ I had that sig for over a year. Really annoyed me.
If I could do 1200 on 1.25v or less I know I have a good clocker, at least in my opinion
Your sig is pretty big and bold. I disapprove.
Being able to reach 1200 is pretty good in my book. That's more than fast enough.
Will trust you the relevant info.
EDIT
Petey, Tommy, you better not hang about i can see these things running out of stock.
Don't worry about me mate. My heatsinks were fine in the first place
Pff you know you want those heatsinks Pete and ive got the email to prove it.
Is this better matt?
Had to cut it down a lot because of the 1000 char limit.
It burns my eyes.
