i am not too worried about clearance, It might actually be better if the main heatsink applies some additional pressure on top of the vrm heatsink since it will improve the contact with the vrms, as well as providing some additional thermal transfer directly between the main heatsink and the vrm one. It won't work very well if its too big though as it may end up bending the end of the video card.

The gelid kits comes with a thermal pad, i might just have to use that if its what its designed for, I just hope it works better than the akasa.
 
Sure, but I'd still get some thicker pads. The included pad doesn't even make contact with the VRM's and the 1.5mm put minimal, if any pressure on them.
2mm is the way to go unless you grind down the side bits.

EDIT: The added pressure from the main heatsink probably wouldn't do much imo. The gelid sink is pretty sturdy and won't simply bow under the AC :D

Just gotta love AC's postage pricing.:(

Going to put one of my spare 5870 Extremes onto the DD my friend got off me as the temps are simply ridiculous tbph and went to put an order in for another mounting plate/screw set for the trusty old 5870 Extreme.

So I thought I would throw in an extra spare set of screws/washers/sticky washers and the postage jumps up another extra $7.49-for simply adding another teeny tiny bag of screws, that will come in the same package anyway!:eek:

Sent them an email query so I'll wait and see what they say, but I imagine I'll not be getting a spare set of screws due to their rip off postage.
 
Damn, i think i killed my card Q.Q

Gotta go to work now, but so far the PC turns on with no signal detected. Its an intel 2500k so i think the only reason the PC turns on is because of the integrated card. I got the gelid part, sanded it down, cleaned the vrms placed tape on any areas where it would touch anything conductive and basically covered all my bases but alas no signal detected.

It did this once before, basically what happened was i forgot to firmly push the PCIE cable in and until i did that it wouldn't post but i double checked the cables this time and still nothing.

Anyways, after proper testing tomorrow i will have a firm answer... but what a crappy way to start my work day :( hours before Infinite launches too...

Oh dear. Are you 100% sure the gelid sink did not touch the AC main heatsink? This puts me off doing it with mine. Heard a few reports that the Gelid heatsink is killing gpu's left right and center. :p

There was a lot of clearance between it and the artic and i'm sure even if they touched it wouldn't result in anything bad.

No, something else happened. When i get home and open it up again i'll know for sure. Right now my working theory is that i screwed it on too tightly - happens with some waterblocks that when you screw it on too tightly it doesn't show a video signal. Anyways that's a best case scenario.
 
well i got the beast to work once more :D turns out the i screwed something on too tight. Either the Arctic sink, the Gelid sink, or the two screws that hold the PCB into the PCIE slot.

Problem is i killed one of my VRM sensors :/ LOL how ironic... anyways GPU-z reports VRM2 at 0c all the time.

Problem is, i only fiddled with the area where VRM 1 was located, never even touched VRM2... I don't know if GPUz is reading VRM2 as VRM1 or if VRM1 is indeed VRM1 and that sucks...

For all i know VRM1 could be at 100c when i'm reading 80c in GPUz.

So you reckon screwing the gelid down onto the vrms damaged one of the vrms or all of them? Vrm 1 is the long line of vrms isn't it?
 
Spoke too soon.. I saw smoke Q.Q it's definitely dead this time.

Cleaning it up now and going to attempt an RMA - worst they can say is no.... I'm at a loss for what to do. I have a 570 i can use until i come up with something. No new cards coming out soon right? Thinking about grabbing 2 GTX670s and calling it a day. The reason i bought the accelero is because the 7970 is so damn loud. If i get a replacement - BIG if- it will come with the loud stock cooler again and i won't risk another install of the accelero.

So maybe buy a 670 now, wait for RMA results and if i get a working one i sell it and get another 670 - less power draw, and less noise than a 7970 CFX, for about 10-20% less performance.

$350 7970
$100 Accelero
$10 heatsink

all gone because i screwed it in "too tight", Computers can be harsh beasts....

Oh dear god. Must have been a short. But how?

My VRM temps were higher than before and i figured it was because it was too loose, so being the genius i am i tightened it up little by little testing to see if it would post and then i guess i went half a rotation too many and away she went....

I don't recommend this VRM heatsink :p basically you're playing a dangerous game trying to find out "how tight is tight enough". Very sad, this month my Headphones broke, Laptop Charger stopped functioning, My GPU blew up... :rolleyes:

Yeah i really want to try it but it sounds fraught with danger. What i really need is a tommy or a petey to try it but i fear that will never happen.
 
That's horrible news mate. I really feel for you :(

Sorry Matt, never gonna happen. Even if I wasn't going for WC, the beast is the only one for me on air :p

Just don't tighten it down too much if you do try it.

But how tight is too tight? I'm starting to think this is a bad idea.
 
I'd say to just look at the compression on the thermal pad and judge it accordingly. It doesn't need a death grip.

OR, you could just be happy with the great temps you already have and stop worrying about getting literally a few degrees less? :)

Also, Peter may be looking for a new home in the very near future. With a couple of GT's underneath, it matches VRM temps with the multi-fanstravaganza setup and only loses by up to 6c on the core.
It looks rather swish too IMO.

Man, that TY-140 is ugleh!
