ASUS GTX580 DCU-II Fan problem - Page 2

post #11 of 28
It's not complicated at all, took me 30 minutes to do two cards. Check out the temperatures and resulting noise levels. I went from idling 40-50C (these are MSI Twin Frozr III coolers, highly efficient) to 30C and loads went from 80C+ to 55C max. Not to mention the fan noise under load was unbearably loud before. It's 10 zip ties and done wink.gif

The DCU II is better than the Twin Frozr III in terms of cooling, and quieter too.

I've had a GTX 580 DCII, 6950 DCII, and a GTX 570 TF III. Both of the DCII cards idled in the low 30C range and loaded in the 50-60C range in 3DMark11. My TFIII 570 idled in the mid 30s and loaded at slightly higher temps than the DCUII. Yours probably had bad contact if you were getting 40-50C idle temps.

Here is the idle temp (32C) and max load temp (62C) for my old DCII GTX 580. The 62C temp was recorded during a 3DMark11 run at 930 MHz core.

So there is absolutely no need for OP to void his warranty and go with a water cooling system that can leak (yes, the sealed loop systems can leak, just do a quick google search). Best thing for him to do would be to either lubricate the fans or RMA the heatsink.

how would i lubricate the fans? how does it fix the "broken" fan bearings?

should I take a picture of what I can disassemble?

Just unscrew the fans from the housing. You have to reach a screwdriver in between the fan blades to get to the screws.

Not trying to be the "don't void your warrranty" ***** here ( I disassembled my GTX570 myself because of a few spilled water drops) but I would just RMA it and get a guaranteed fixed card back. Why spend the time and perhaps mess things up further (and possibly lose your warranty).
Just my opinion.

OP: you might want to fill in your rig details, it's easier and good for the epeen thumb.gif . Perhaps you have a SB and you can use the iGPU while waiting on the RMA return.

It's a new comp, just got it a month ago

i5 2500k
asrock z68 ex3 gen 3

something like that works with my non reference model but I assume i need something like the corsair hydro series h60 for them to work?

yeh i think the i5 2500k has some inbuilt hd 3000 but dont think they can handle sc2/dota2 frown.gif

okay, will go and buy some sewing machine oil as suggested, hopefully itll work!

thanks! +REP

also did you try that before you RMA'ed your previous cards?

My idle temps were high due to SLI + GPU accelerated browsing. The mod does not technically void your warranty any more than any other aftermarket cooling solution as you're simply removing the stock HSF and replacing it with another cooler. Regardless, I'm not here to preach, I was simply suggesting what has, for me, been a very successful modification. Bottom line is, he'll get better performance/noise at a cheaper price going with the Kuhler mod vs any other air cooled aftermarket solution, which is what he was considering in lieu of RMA'ing the card.

OP, have you tried calling Asus to see if they'll do an advance RMA for you? That would ultimately be your most hassle free option.
