Hi all, first post here but I'm diving right in with this mod.
I saw this thread a while back but just now I'd had enough of the jet engine GPU I had in my otherwise very quiet PC.
I have an MSI 7870, and although it has the dual fan design, it still got loud and hot, as it's similar to but not quite a Twin Frozr model.
I sucked it up and went to Best Buy and got an H55 because it was on sale and all they had. It was $50 and I had a $20 gift card, so I figured it was worth it.
After spending about 40 minutes installing the thing (you need 3 arms to do it right it seems
) I got it secured with a bunch of zip ties. However, I had to go to work, (I work a weekend job that's not even really a job to save up for a band trip in the spring. I supervise a gym that's open to the public, so I can have my laptop here.) where I'm posting this from. I didn't have time to slap it in and test it yet, but it felt very secure and didn't wobble when I picked it up by the pump/water block. All I had time to test was the pump noise, which was actually almost nonexistent. I'll happily take the quiet hum of the pump over 2 little jet engines in my case
I just attached 3 zip ties around the circular block/pump and attached 4 ties to that which ran down the screw holes with 4 of the little zip tie ends to hold them in place. Seems to be OK.
This is the picture I got as I ran out the door. Sorry for the iPhone quality.
I'll get more pics if I get it up and running, but I couldn't be late and this is all I had.
As far as VRM/RAM cooling, this card didn't have any besides the GPU fan kinda blowing on it through the fins. I never had issues so we'll see how it goes with the very scientific method of putting my finger on them and seeing if I get burned. I've got a front fan giving this fresh intake air, so that should help some. My overclock doesn't take me far off stock volts, so it should be OK. I had it at 1240/1241/1.26 volts I think. But, it was hitting 80*C when Bitcoin mining and the noise drove me insane. The heatsink was making good contact, as the heatpipes were very hot, but I just got a hot card I suppose. A 200 mhz overclock + an overvolt doesn't help I suppose, even if it's not too extreme.
If it gets bad I guess I can creatively mount the shroud back on so everything gets some airflow.
I also noticed that the cold plate wasn't exactly flat. I decided not to break out the sandpaper unless I'm not satisfied with how it performs. I'm not sure if that convex-ness of the cold plate made the difference, but I didn't have any issues making good contact with the die, or so it appeared. The block is only so slightly sitting above the metal thing (not sure what it's called. great way to put it I know..) that forms a rounded rectangle around the GPU die itself. Regardless, it's making decent enough contact to where it should at least boot easily without catastrophically failing. I'll keep an eye on it when I boot it up.
I guess even if cooling performance is only say 10* better I'll be happy because it'll be quiet. Also, one of the fans on my 7870 made a clicking noise that was kind of annoying, which will be lovely to get rid of. I guess if it doesn't work I could let my parents use it in their office PC, which is horrendously loud to me even through a wall, or try it on my FX 8320 to free up some space taken by my heatsink that only mounts vertically on AM3+, which is undoubtedly hurting performance by pushing hot air into a wall on my 550D case.
Even a 140mm exhaust didn't do much over the original 120mm. It's at 4.3 Ghz on stock volts, so this shouldn't have too much of an issue cooling it if it comes down to that.
Also, I have a nice 120mm Phanteks fan that should be a lot better than the included H55 fan. I'll compare the 2 after it's up and running for noise. I think I'm getting ahead of myself here, but whatever I guess. I just don't want anything broken, above all.
We'll see how this goes! As I mentioned, more pics should be coming this evening!Edited by Spencer12 - 11/24/13 at 12:58pm
