Well the results are in and lets just say that it was a much more involved upgrade than I originally thought that it was going to be. While I had originally planned on removing my cpu heatsink to apply MX-3 to it, I had no idea that the VRM-R2 would make contact with my 120x38mm Panaflo (which I had also planned on making a shroud for). Ultimately, I changed the fan from a push to a pull configuration and based upon what I have read in the forums here, that's going to cost me 1-2C in the end....

Sorry for the length of this one, but I felt it all needed to be said and included. Well, I've gotten a couple of responses from ASUS Customer Service (I'm assuming they're located in Taiwan given the guys(?) name). Here's the first email exchange:

Well crap, I'm going to have to postpone putting the Thermalright T-Rad2 GTX & VRM-R2 onto my EAH4890 to help with my uncomfortably high temps, OK, they're high to me with 60C idle and ~75C when I game. This morning I opened up my case to get more air flowing to it during a 30 minute OCCT GPU test to get the maximum load temperature and low & behold, there's a LED lit up on it. I couldn't be lucky and have it be D1601 (critical temperature) or either D1602 or D1603 (power connectors A or...

OK, I've calmed down some now. I've managed to get my OC on this guy back up to 940/1140 @ 1.4V with no noticeable problems atm. Friday, I went ahead and ordered some more parts, mostly for cooling this heater down.

I've got a Thermalright T-Rad2 GTX & VRM-R2 coming from SVC.com and some Arctic Cooling MX-3 that has already arrived from Petra's Tech Shop. I also went ahead and ordered 2 Blue LED 110cfm CoolerMaster fans ($5 a pop, ), 2 80x25mm high volume fans (80cfm...

Alright, I'm getting severely po'd at this ASUS EAH4890. When I got it, I could OC to 975/1150 @ 1.45V with no problems and I ran Furmark for 1 hour. NOW I'm at 900/1050 @ 1.35V because about every 2 weeks I lose my OC due to severe artifacting. I don't think I'll EVER purchase a ASUS graphics card again and IMO they are complete garbage. I've had it 3 months and the first 3 weeks were awesome, now I fear that by the end of September all it will be able to run are stock speeds and by the end...
