Core - 1215 MHz
Mem - 1652 MHz
VDDC - 1.119 v
GPU Temp - 73c
VRM Temp - 91c
Well, the more voltage you add, the more heat there will be. Now a lot of people here will tell
You that the Vrms can go to 100c and be fine. (Of course not 24/7 @ 100c)Anything above 80c on the Vrms makes me a little nervous. Quick rule of thumb, the Vrms temp Is normally about 20c more than the Gpu temp.. A lot of guys here are water cooled so there's less worries with that. If your gonna flash your bios and do the volt mod, your gonna have to figure a way out to keep your temps down. I used an aftermarket heat sink with some Corsair SP 120 mm fans and some micro fans on my Vrm heat sink and I range around Gpu 50c and Vrm 70c clock speed 1306mhz with 1.25mhz volt. You might have to get creative.

I was interested in an aftermarket setup for it. I have the H240x so I could potentially incorporate it into the loop, but that would cost a bit so I don't know if it would be justified. I would definitely not want to get creative with it though. If i took off the DCU2 I would want to put on a full cooling system. If anyone has one they would recommend in terms of air cooling that would be great.

I would require at least a 15-20% improvement performance wise to justify dropping 200 on water cooling equipment for the 780, especially considering I have no experience customizing a water loop.

Check this out.. This is what I used with Corsair Sp fans and it worked awesome got me.. RAIJINTEK MORPHEUS CORE EDITION, http://www.newegg.com/Product/Product.aspx?Item=9SIA66Z28H1378

here's what I did to my card.. [IMG]
post #24425 of 24924
I certainly would like to get that kind of performance from my 780, but thats a lot of creativity for me. Last time I tried to get creative with mounting options I just ended up with a mess. It might be a long shot but are there any heatsinks that are designed for this specific card? Or am I going to need to resort to a water block to get the uniformity I am going after?

Now that I saw the VRM temps I am worried this card is losing a lot of its lifespan. Should I dial down the clock a bit? I made a few adjustments and got the core temp down to 68c, but the VRM temp doesn't seem to go down with it.

Well water cooling is the best hands down. I don't think the 240x can handle a Gpu along with the Cpu, especially if it's over clocked. You might not lower the temps as much as you want them to be with the 240x. Most likely you would have to add a small rad in with a fan before the Gpu on the loop.. Lotta work and more money.. The Raijintek heatsink is a universal heatsink. It's made to fit the ASus Dcu2oc and many other cards.. In the end, I'd wait it out and probably save for a 980.

Oh yeah I would need to get another dual fan radiator to handle a graphics card, and then the waterblock on top of it would bring the entire thing to +200 USD, and that woulden't get me a huge performance increase. Selling my 780 DCU2 and buying a 980 would net me a hell of a lot more performance for my dollar.

Putting more effort into my testing with my current rig, it looks like if all my fans are maxed I can get a lot lower temps. 57c Core, and 72c VRM to be exact, but it is loud as hell. I might need to reconsider fan placement before putting a lot more thought into modifying the card anyways. I might just be starving the card of cool air since I don't have an intake fan next to it.

have you changed your thermal compound? That would help with the Gpu temp..is your card clean? Is your PC clean? Can you add a side fan pushing cold air into the card? Can you overall make better airflow in your case?

I have not disassembled the card whatsoever since I bought it. I am a bit worried about voiding the warranty doing so. My system is a positive pressure system so things are staying pretty clean in there. I am in the process of installing a side fan in, but I need to wait for a really long extension cable comes in for it. Just gonna need to zip tie it on the side because the 730T Graphite Series doesn't have an official fan side mount. Temps dropped dramatically with all the fans at max, so I think adding an intake next to the card might give me a little more overhead.

I don't think the warranty is void on that card if you change the thermal compound. Send Asus an email and see what they say.. It's only a 2 yr warranty? Right?? I used this TC. Rated top 5 on the market http://www.newegg.com/Product/Product.aspx?Item=35-242-027
Also the heatsink tends to get loose over time. It might not be sitting on the Gpu as good anymore. I'd look into that. Make sure PC is squeaky clean, make sure your card is super clean, add side fan and make sure you have great airflow. Move some cables around if you have to in order to get better airflow,
