ShadowMAN280xI'm concerned that maybe the thermal pads work better under pressure... despite the benefits of direct contact cooling, the backplate puts a fair amount of pressure for the pads.
Dabadger84Welp, unfortunately it looks like that did a little good, but not much: I'm gonna go back to using the backplate, too much concern for too little improvement going from backplate to direct contact pads & heatsinks.
pclausenHow are you guys getting HWiNFO to show mem junction temp? All I see is this in the Sensor section for my KingPin: My KingPin also just shows up as a generic EVGA 3090. Elsewhere HWiNFO does pick up that it is a KingPin: I'm on the latest driver and HWiNFO version. Thanks!
pclausenThanks found it. Looks like I need to up my game for cooling the backside:
DZelmer Your actually using a newer version than i am bata build?
Dabadger84 How the heck is your PWR5 that high lol what. That's crazy. Even stock, I don't think mine ever got over 40C or so. Did you do any pad changes or additions under the backplate, or just the heatsinks on top of it?I'm guessing the GPU hot spot is new for that version of HWinfo? I don't use the Betas, I wait lol
pclausenI think I found out what part the issue is. The fan on the card barely spins. When I set it to manual in PX1, it only spins up to 2,500 for a few seconds, then goes down to between 0 and 800 or so: When I just watch it, it alternates between not spinning at all, or spinning just a little bit before stopping again. When I attempt to control the fan speed from Afterburner, I get the exact same behavior. It will spin to 100% briefly, then go back down to a very low rpm. I'm running 6x Noctuas in push/pull on the rad. I wonder if that is somehow messing up the single on-board fan?
vulcZ Are you running Phoenix Miner by chance?
pclausenvulcZ Are you running Phoenix Miner by chance?Yes I am. I also run Awesome Miner on another machine (VM actually) that controls all my rigs, including my gaming rig. I think I see where you're going with this. I suppose it is possible that is what is causing my erratic fan behavior. Per my follow up post above, I seem to have found a way around it by setting up a flat curve in PX1.

Per my follow up post above, I seem to have found a way around it by setting up a flat curve in PX1.I always set custom curves right off the bad i found fan 1 is the rad fans and 50 to 60c and fan2 the one on the card 40 to 45 c seems a good spot i leave the low at the stock spot and del the two points in the middle and have it max out around those temps. Px1 is still quirky and after a restart or of it crashes even if it loads a profile it dosen't apply it i have to reload it with the miner running or a benchmark then start the benchmark over again the miners see to be ok with adjustments on the fly. And the little box by the fan curves has to be checked for auto fan control to work the little fan button next to the manual controls dosen't seem to do any thing...buggy px1 still!
