Custom water cooling / full cover heatsink project on Radeon HD7950 XFX Double D in Wooden Case (with pics)

post #1 of 6
Thread Starter 
Hi guys I'm new here and decided to introduce myself by posting pictures of my lastest project!

So I run an NMediaPC 8000 wooden computer case for my gaming rig.

http://www.newegg.com/Product/Product.aspx?Item=N82E16811204039&Tpk=nmediapc%208000&IsVirtualParent=1

Specs:

Fx-8350 Overclocked to 4.4ghz
16gb crucial ddr3
256gb crucial m4 ssd
1TB WD Black HDD for storage
2TB WD Black HDD for recording
2 x XFX Radeon HD7950 Double D in Crossfire(when necessary)
900W Antec High Current Gamer PSU

Needless to say, this thing has absolutely awful heat problems. I could solve all my issues by buying a new case but screw that, I'm stubborn and I love my wooden box!

I liquid cooled the cpu which cooled it down significantly. Still, the case was running very very hot. So I cut two 120mm fan holes in the lid and covered them with black screen and a brass/bronze cover for a floor register to keep with the steampunk-y look.

This helped quite a bit more but I wanted cooler. Next step, liquid cooling my GPU!

Now, this is where I couldnt justify spending a fortune. I wanted to just get the Arctic Accelero Hybrid 7970 version but they want $160 for it and I'd still have to glue little heatsinks to my memory chips which i really really didnt want to do. The generic Accelero Hybrid was $100 which was alot more reasonable with the caveat that i'd have to cut or buy a copper shim to make it fit in the sunk in gpu area. No big deal and I'm willing to take the hit on the efficiency of it.

Now I keep looking and find that switech makes a full cover heatsink that's made to work with their waterblock. It runs $40 plus shipping. I really liked this idea for cooling the memory chips and rest of the card(plus it just looks WAY cooler). Since it was made to work with a different waterblock I knew I was going to have to do alot of dremeling but thats okay. I like having an excuse to use my Dremel smile.gif

I had a $30 gift card to Newegg as it was. I got lucky and managed to find an open box product of the generic Accelero Hybrid for $70. I do this stuff for a living so I was willing to risk it and had enough parts laying around to make it work if I had to.

So I pulled the trigger and bought the heatsink and the open box hybrid. Total investment after shipping was about $90.

Once everything arrived and I got to see what I was working with, I found that the Accelero Hybrid is really just a Kuhler 620 with a nifty little bracket screwed to the bottom of it(totally removable) so that you can mount it to a graphics card. My package only had one bracket which I assume is normal. It mounted right up to the holes in my card with no issues but I had to cut the bracket down to size to fit in the area alotted in the switech heatsink. I also had to cut the area on the heatsink larger to help accommodate the bracket. ALSO I had to dremel off most of the plastic bits on the waterpump itself that are unnecessary in this configuration(they're used by the Kuhler 620 to rotate and clamp into the retention ring which we dont have and arent using here). I also had to grind down a bit of a slot in the heatsink for the water pump hoses to fit through as they were just a bit too tight but it was no big deal.

I'm going to sand it down and paint it eventually but here we go. The part you've all been waiting for, PICTURES!

Once the card was done came the problem of physically mounting it in the case. I wanted to mount it on one of my 120mm lid fans but ended up not being able to as the drop would make it hit the hard drive shelf. Ultimately, I came up with this. I set up a push pull configuration on the cpu radiator(there's a 140mm fan on the other side of the case and a 120mm in between the radiators) and bolted the radiators together. It runs no where near as cool as it could and should but given what I'm working with it's all I've got for the moment without making major modification to the case. It's still running way cooler than what it was under air cooling so I'm happy with the result.

*

And finally, the finished product with the lid bolted on!

*


The card as is idles at around 45C which is significantly better than the 60-65C it idled at before(with both graphics cards installed). Under full load at 2560x1600 maxed out on Heaven benchmark it tops out at 71C. Previously it would hit 100 or higher! I believe I can improve this by about 5-10C by rotating the radiator locations and cooling the graphics card first. It's going to be alot of work and I'm going to test it out a bit before I do it. CPU idles at around 35C in this configuration. Anyone wondering, yes TIM is applied on both top and bottom of the copper shim and the video card idles on a test bench at about 27C by itself. TIM used is Siig Ultra-Chill Brush-On Diamond Thermal Grease(first time using it, very impressed!).

Well, that's it! Questions, comments, suggestions are welcome! =D

Wow, very good, but why didnt you save money and buy the 620 on its own?

Nice mod smile.gif You will drop an easy 15c by separating the rads, but I understand the lack of room in an HTPC case. I know the air coming off the rad on my H70 is pretty hot, the poor little rad struggles with the heat and its the thicker version too. The thin ones must be very hot.

I love that swiftech VRM/GDDR cooling plate and wanted to use one, but it won't clear the fan mount on my TripT bracket since its too tall frown.gif.

Cut into it a bit with a dremel?

Why not make a simple extender with some rivets and a bit of metal?

The whole section of fins would need to be cut - the fan mount on the bracket sits low to the card, just above the power connectors.

It wouldn't clear by a lot frown.gif. To space the higher bracket would be a royal pain, I would need to get a circle cutout ~3mm thick with all the notches matched up and that's not happening without access to a mill...and then I wouldn't be able to fit a second card under it with a fan installed anyway.

After everything was considered I figured it was more trouble then its worth for my particular setup so just went with heatsinks smile.gif.

looks very good!

i would love to do this to my 7950 and the same when i get my second, with 2 antec khulers in series would be very cool

just wondering, what pcb do you have? do you have the original reference one or the revised xfx one? i think the revised one is the VPEAC3861PS8 board

i would love to know haha

thanks
