Had the same mod on my 7950, and it was brilliant, what makes it even better with the 290x series is you no longer need the copper shim.

Furthermore I have close friend has just ordered two 290 to replace his existing crossfire 7950's that were also running via dwood brackets and antec 620 solution.

Hopefully get him to post some images of how they run in crossfire with temps + vrm temps

Under construction....

Done a bit more reading on VRM heatsinks, it does seem that a lot of people use them

What I don't get is why my old cards, GTX 480, HD 7950, HD 7970, Nvidia GTX 780, Titan etc all ran fine with this mod and no VRM heatsinks, if it so important, how come they were fine?

Anybody know where I could pick up the heatsinks for VRM's on this 290X?

What about VRM heatsinks? Would have thought they get hot as hell!

Somebody linked a kit they had bought in another thread I think, might have been this:

http://www.overclockers.co.uk/showpr...odid=HS-038-AL

VRMs are rated for 100C+ so I guess if you had any kind of airflow in your case they were kept cool enough from that? I have heard that they may work less efficiently when near their temp limit, perhaps you could've got better OC's this whole time if you cooled em.

Please read the FAQ regarding signature sizes

Haha very possibly . Thanks for the link, trying to find VRM cooling small enough for the 3 at the back of the card.. Everything seems to come with custom coolers, hard to get separate bits..

VRM1 temps @97c is that with the VRAM Chip Coolers ? I think if you can get that down you should be able to overclock more or be more stable at least that is high but i think people have been saying they could have a limit of 125c but i dont know if that is 100% correct. lovely mod for sure.

If that is not with the VRAM Chip Coolers get some on it

Yeah that is without any heatsinks on the VRM. Done a lot of reading and it seems that at higher than 100c VRM's could effect overclocking. Bearing in mind that test was done at stock settings, so I'm def gonna take the advice from the peeps here and get some VRM heatsinks. Only problem is I can't find any low profile ones that would fit under the Kuhler fan bracket..

I found that VRM 1 is the front part of the card with multiple VRM's and VRM 2 is the rear 3 part. Cooling likr this in the pic would be ideal, but only seems to ship with retail Artic Accelero 3.

You could always buy some normal ones and cut the tops off.

Ty, what can you use to cut them so it's a decent clean cut?

Dremel, hacksaw, jigsaw + vice / clamps? I would wonder about reduced effectiveness though.

Why not get a proper loop with a full size block? This will then cool the vram.

kinda hard to get hold of a block currently.
and christmas is up also so dont expect things to improve so fast.
I did a similiar mod, used a vga block for core and using 2 fans under the card to cool the vrm. while not optimal until a full cover block is widely available this will due for now.

I am going to say the reason is cost. This mod cost him nearly nothing as he had most of the parts already i think. If you want to go custom loop you are looking at 400-500 pounds and for some people its not worth it / too expensive. Plus its fun to mod

The reduced effectiveness would be a factor with purpose made smaller heatsinks just due to their size. I'd imagine something is better than nothing.

^^ This.

I've ordered the heatink set (http://www.overclockers.co.uk/showpr...odid=HS-038-AL) from OCUK that teppic and orangey recommended.

If worst comes to it, and it doesn't fit under the fan bracket, I'll try a different bracket without fan mount, probably better to fit heatsinks on memory and VRM with no fan than to have an fan cooler with no heatsinks right?

Will update the thread when it's done.

http://www.overclockers.co.uk/showpr...odid=WC-458-EK just saying.

I'd of thought Block, Pump & Res, Rad + tube & connectors could be had for 2/300 + 75/100 more if you want to do the cpu as well.

If you have the existing parts already then fair enough.

My prolimatech cooler comes with some tiny vrm heatsinks that I don't need, you can have those if you want.

Thanks man, I appreciate the offer. Will see how I get on with the OCUK heatsink kit, hopefully be here in couple days. If they don't fit, that would be great of you to let me try them

mine, zero as I had all the stuff at home from previous set ups.
new block would be 100euro or so.

I'm about to embark on this same mod, albeit without a bracket...trusty old cable ties for me on an R290 (hoping to become an R90X ).

I've been trying to find out if you can leave any part of the stock heatsink on with the cooler? basically the fan i would like to keep.

middle pic - can you just remove the main heatsink in the middle? http://www.guru3d.com/index.php?ct=a...n=file&id=7148

Failing that looks like I will also need some RAM heat sinks.

Heatsinks arrived today, very fast delivery, even got some haribo :-D Thank you OCUK.

Just some sinks on VRM1 part for now as VRM2 is 50c under load seems pointless adding heatsinks...

Think it's knocked about 10c - 12c off the temp. Do these temps seem safe?

So how much cooler are you VRAM's now you have heatsink on them? 97c to beat!

Using the same test @ full load down to 87c. I'm guessing that's got to be a good thing.. Longer gaming sessions hopefully temps will stay sub 100c.

I think 90C or under for 24/7 is fine. At least thats how it was with Tahiti vrms. If you went too much past that stability could sometimes become an issue. All depends what vrms are used on the 290. The good thing about the reference cooler is the blower sits right on top of the vrms so they always remain the coolest part vs the core.

Awesome job really surprised ATI did such a odd job with their cooling this job round hopefully 3rd party coolers and manufacturers will fix it.
