MSI GTX 970 performance bottlenecked by temperatures

So I have had my GTX 970 for a long time, but just realized that it is being bottlenecked at around 58C maximum lately (used to go higher). I have noticed this when doing both the heaven benchmark and also doing GPU heavy tasks in Linux it will underclock a lot to keep at the 55C mark. Is there a setting somewhere to raise this ceiling? My card basically idles at 55C right now so core clock speeds are at about 700MHz. To see if this gives anymore info, I remember my card idling at around upper 30s to low 40s and now it idles 10C hotter, though I assume that is happening because the paste is just over a year old?

The paste should hold way more than a year, depending its quality of course. Have you updated/changed the bios settings or the fan settings of the card? Do you hear any different sound coming from the card , like a bad fan?

You could check with afterburner if anything have changed on the card's settings.

The hardware is completely in tact with no bad fan sounds or anything of the like. I haven't modified anything on the card except for I did an overclock. I am hitting about 65C right now but the ambient air temperature is also about 10C warmer too. After doing some more monitoring of how my card behaves with different software, I find that it's only with a few applications in Linux so perhaps the software that is being used is to blame and not using my card properly?

I assume that the entirety of your problems are unfortunately linux based. Drivers as you know are a big problem in Linux and for some reason the power aspect is always getting the worse. Another thing that needs confirmation is how accurately the monitoring software works under linux. All these are designed to work under Windows so the software or the sensors might not work as should.

If anything I would blame the monitoring in the drivers or the Nvidia control panel. They seem to have removed overclocking in Linux (or I'm doing it wrong) and maybe there's a setting in the configs somewhere that would let me increase the ceiling if it is indeed set at a low spot. Like I said it only appears to be based on certain applications. I find performance to be about on par with Windows in terms of gaming. I would find it weird if Nvidia seriously gimped their Linux drivers though since there are some Linux supercomputers that use Nvidia, but who knows
