So I have a 570 with the Thermalright Shaman. It's quite awesome; on Arhkam City it stays below 50C.
The GPU, at least.
On my 5850 I could read my VRM temps on GPU-Z, but now I can't. I can't find a single application that will read my VRM temps, and it would definitely be dangerous to overclock without knowledge of my VRM's.
I've tried NVidia System Monitor, HWmonitor, GPU-Z, the whole lot.
Is there anything that could read my VRM temps?
Could I possibly proceed overclocking without knowing what they are?
I like how that ATI uses fully digital power vrm all the way through except for the caps and chokes. The problem with nvidia is that they often use very cheap low quality parts. The GTX570 is terrible when it comes to quality of the power vrm. The coils often get rather hot like any other card out there however the mosfets are known to fail even at stock volts and clocks resulting in a dead brick. Some are random while others failed during overclocking. You might look into replacing the poor quality stock thermal pads for something much better. You want pressure and no gap between the cooler and the power vrm mosfets. The more pressure the better as it makes for great contact and improves heat transfer a lot like pressing down on a piece of meat while cooking.
It is odd they did not keep the vrm design from the GTX 480, as they can handle voltage all day long with ease.
I'll try to remind the forums here lol, it is basically a repeat of what happened in the old G200a/b days. The old 65nm gtx 260 and gtx 280 had a high quality and fully digital power vrm that can handle 240w out of the box without mods but after the 55nm models came out that all changed. The cheaper analog designs couldn't handle the loads as well despite a cooler running core with lower power consumption.
Indeed it is based plus they wasted good low amp low watt samples that could have easily made overclocking monsters. Some of these samples could have gone over 1ghz on a stock retail gtx 580 board. The card is built cheap and was a risky gamble. So is the rest of the dual gpu Fermi era cards. GF110 is known to power surge easily drawing over the rated current for what the power vrm can supply. The GTX590 can easily crack 550W even when OCP and OVP are enabled even on stock volts. That is why they burn.
