As to me it seems to bend up at the right end... I need to find right height for its support bar. its probably too high on the right.
Just based on the photo, it does appear to be sagging a bit. Would definitely recommend a support bar, you can get adjustable ones for cheap online.
Components can start to fail, not just heat related ones. Same applies to motherboards too. Longer you use them, more chance something will stop working right.
Yeah, my whole rig is around 6 years old. I built the main rig Dec 2018, got the RTX 2060 maybe Feb-Mar 2019, added some storage over time, replaced some case fans, and got my Ryzen 5700X last March. I would like to bank on this rig for at least another 1-2 years, so maybe picking up a cheap but reliable PSU would be worth it, and perhaps a new CPU air cooler. Mine is of course 6 years old and is far from being the best one around. Gamer's Nexus highly praises the Thermalright Pearless Assassin 120 and it's only $40 USD on Amazon.
I went ahead and picked up some new thermal paste and thermal pads. I ran HWInfo last night while running multiple benchmarks in Cyberpunk 2077 with higher graphics settings than I play on, and it stated my GPU hotspot temp reached 92C. Uh oh. Beneath that line, it mentions the max temps for GPU and "hotspot" are 83C. Of course it can go a bit higher but that is max normal operating temp before clocks start to slow down.
Normal temps for me typically don't reach 83, but I have seen a few times in the past it hovering right around 80C. Pirate Yakuza sits right at 70C, which still seems a bit high for a not very graphically demanding game. I have custom fan curves set to blast at 100% when it reaches 70C, so I'm chalking it up to the paste and pads.
As I mentioned before, I have repasted my card at least once a year for the past 2-3 years. I have never repadded it, so I wonder if those are no longer working properly. I would assume so, since a lot of resources I found online suggested changing thermal pads every 3-4 years as a rule of thumb. I've never done it before so I'm a bit nervous but it will be okay. Just need to be very careful, and one person suggested using tweezers to help hold the pads. I also need to pick up an Xacto knife and some compressed air.
I hope I got enough thermal pads, my card uses 2mm thick pads, but the brand I wanted only had 1-1.5mm, but stated you can stack without performance loss. I got two 100x100x1mm sheets, $8.99 each. I need to stack them, so I hope that will be enough for everything. I just need to not rip off the old pads before applying new ones in case I need to order more. Nervous, but I know I can do it right, just gotta take my time.
