AMD Phenom 2 X4 965 @ 3.4 GHz
Radeon HD 7950 Reference @ 925 MHz & 1250 MHz (Sapphire)
ASUS M4A89GTD PRO/USB 3
Corsair Dominator GT 8 Gb (2x4 @ 1600 MHz)
HX 1000 W PSU
H60 (CPU) & H75 (GPU)
In Win D-Frame (190/500)
SanDisk 240 GB SSD
Microsoft Windows 7 x64

So that's the rig. I already get 40 something degrees on my cpu at 100% load. So now I did the same on my gpu. I'm now running 40+ at full load. Sorry for the pics, taken with iphone 5.

This is the first run with the H75 cooler, d3CPx33c.jpg BF4 on low, I had it set this was due to gpu running 97° @ 22% load. Vikings season 1 episode 1 on putlocker with firefox. I had removed the brick (oem cooler) and cleaned off the themal compound, this caused the insane temps at such low loads. Upon replacing the brick, the fan would accelerate to max rpm and it sounded crazy. I don't have any pics of that, because I simply shut off the pc and let it cool.

This is a set of pictures of what the card looks like, Azhv3I0y.jpg GuVSY5X1.jpg eDNk0f91.jpg iJbOGqcN.jpg L6dcrOQG.jpg as you can see the oem compound, was actually some kinda tape and stickers. Some of it resembled playdo.

This is what the cooler looks like, y2JrpfJD.jpg I had to get the rounded block due to 55x55 mm bolt pattern. cGrbsCdh.jpg wAMRZOfX.jpg DCXjiyWl.jpg Some clearance shots.That brick weighs a lot.

All I did was drill some holes in the intel bracket that was already on the block, 7jQDrHHI.jpg I had to mark the pattern first, by using the X shaped bracket that came with the brick.

I bought some 1" bolts from Home Depot, some rubber washers and some steel washers, some nuts too. CpHNtEvZ.jpg QP0sMy1c.jpg M1QGlSeq.jpg EFjdRcv2.jpg Sk4mx6Qo.jpg

I'm just letting the radiator rest on the cage for now, BbwGESDQ.jpg ZDrtJTah.jpg y3CviDJ9.jpg XReTGq0C.jpg

This is idle, sb1qySll.jpg and full load on BF4 on Ultra SIEnE5WJ.jpg. The max spike in the idle picture is from loading. For some reason the temps spike a little during loading, the pumps are plugged into the mobo. Should I get molex adapters and just run them straight from the psu? Also the card is now in the first slot, and it's running @ 8x. Says so in cpuz, and in the CCC it tells me that maximum bus setting is 8x. I read somewhere that I should plug it in the second slot, as it's locked to 16x and the first slot is variable, change in bios. I found no settings in bios from pcie, and I went through it top to bottom. Is this true about the slots? I have a new mobo sitting next to me the Sabertooth R2. I'm getting the FX 8350, I have 8 GBs ram, I'm thinking of upping it to 16 GBs, just to replace everything for a clean rig. Got a legit copy of windows 7 x64 too.

how would I, what software? I'm using hardware monitor and msi afterburner atm. cpuz gpuz obligatory.

edit* what a stupid reply, hang on: vrm 1 @ 47 C and vrm 2 @ 41 C core @ 44 C

what do you think? seems to be pretty cool. I lowered it to 835 hrz and 1200 hrz

Very nice!

If it ends up not working out for you, the H75 is compatible with the NZXT Kraken G10 (GPU mounting bracket).

I played bf4 still on ultra for a bit longer, VRM1 shot up to 53 C and VRM2 to 49 C. I still think this is nice and cool. I'm shooting for longevity without sacrificing performance.

edit* i pressed show max on gpuz and its 55C and 50C for vrm1 & 2 I selected log to file, so I'll know for sure

whats your card? and does overclocking it make a big difference in graphics? is it smoother? at 835 its rendering everything perfectly, with minor stutters at the beginning of the game. its not smooth, but it runs without crashing or bluescreening, like it did with the oem cooler.

I have 2 amd 7950 reference cards. Going from 800 to 1150 definitely makes a difference in framerates. I'd have to do some testing to give you an exact number. I run eyefinity setup so I need the performance for the three monitors.

I don't see any reason why you shouldn't try overclocking them. At least see what you can get out of them at stock voltage. Pretty safe there.

My cards will hit 1150 at 1.145v but for some reason want 1.250v to hit 1200. At 1150 they still stay pretty cool during games. High 40's after playing for a while. I don't use vsync so they pretty much run full load all the time.

I play a lot of black ops 2 and I remember having fps around 110 at 5860x1080 with stock clocks. Now it's more like 150 ish at the same resolution. At 1920x1080 it just pegs the games 200fps limit. Lol.

Just noticed you don't have anything cooling the vram or vrm's. You have a reference style cooler and could throw your heatsink in the oven till the copper heatsink falls off. The you can reattach the heat spreader plate with the fan to help cool those. That's how I'm running mine. Just make sure you remove the fan and any plastic before you throw it in the oven.

Hey, I also noticed in the pic with gpu-z that all those temps were only at 61 percent load. You using afterburner? Even if you aren't using it to overclock it's a good way to monitor gpu usage and core speed to see if you are throttling. Took some fiddling to get both my cards to good usage and no throttling.

yea I have afterburner on, I'm using it to bring down the clocks and voltage. clocks come down, but voltage seems to want to stay at 1.25 on full load. The reason that it says 60% percent is, because I alt-tab to take a pic of the screen with my iphone. So the load drops as well as the temp. But like I said, upon hitting display max, it tells me my roofline. I may try to overclock, but I definitely can run the game at 835 and 1200 for vram. Its a bit stuttery, but runs smooth no crashing. Wait till I get the fx 8350, with the sabertooth and a new ram set. Going to go with 2 sticks instead of 4 for better cooling. I had a cooler on my ram, but took it off, due to it hanging and applying pressure on the socket. So overall I'm happy with the setup so far, budget is limited. As far as the heatsink goes, its so heavy, the oem cooler is currently sitting in the trashcan beside me. I want to get those tiny cubed heatsinks, and just thermal paste them on. Should work, with maybe a fan blowing on them?

edit* what are you core vrm and vram temps with your enclosed liquid cooler and the stock heat plate (mine is black) and fan?
my core gets up to 48C vrms at around 55c and 50C vram, I havent tracked that, wondering how?

edit #2* we should be running the same voltage on full load, 1.25 and taking in the boosted clocks into account you should be running a few degrees hotter. I've noticed that my cooler is next to my psu and is in a corner which is a bit hotter. going to try to push everything forward and space it out for even better cooling. Once I get my 3 pin to molex adapters and 4 molex fans, all that is going to run of the psu directly, will report those temps.

edit #3*

using afterburner kombustor @ 55 fps, temps shot up to 60-55C vrm1 & 2, core @ 48C. my cpu pleasantly at 34C lol, will post some pics with bf4 as a test, maybe 3ds max

upped the clocks back to stock 925/1250. running @ 81C/62C, core @ 60C. bf4 on ultra, no more stuttering, runs perfect. should I be afraid of the heat?

Weird that your card gets that hot. What is the voltage at? My vrm's only get that hot at 1250/1600 and gpu core is still cooler..

core vdc is 1.250V vram voltage appears to be 1.602V vrm at 1.155V. im thinking of adding another enclosed liquid cooler to somehow cool the vram/vrm

At that voltage I can hit 1200 on the core. You could probably undervolt your card quite a bit and lower temps. At 1.094v (stock voltage for my card) i could hit 1040 on the core. Just get some heatsinks and a fan on them..

Also, i flashed the boost bios to one of my bios switches and it sucked monkey balls. Maybe flip your bios switch and try the other one? Gpu usage and core speed was all over the place with the boost bios. I prefer the bios on the oldest of my two cards. Flashed it to both cards after modifying it a little.

lol how do you do all that? right now gpu overdrive is turned off in CCC and afterburner aint running, so its at its stock clocks 925 1250. i cant find any settings in mobo bios for pcie. so i have no idea how to change voltage, afterburner doesnt seem to work

I use the beta version of afterburner. I like the extra features. It should let you change voltage. Or Google afterburner /xcl
