Is it worth to change paste?

[PaniVirusGR]

I will go straight to the point.

I have a Sapphire RX 5500 XT Pulse 8GB and I used a OC bios on it. It is stable but the temps on the hotspot is 95-99 oC with the GPU temp being at 70 oC on full load. If I change the internal paste for one THERMAL GRIZZLY KRYONAUT will that help? is it even worth to try for LIQUID METAL (THERMAL GRIZZLY CONDUCTONAUT to be precise)

Generally going from a standard paste to an enthusiast paste in a situation where the original paste isn’t bad will buy a few degrees. If those few degrees will make a difference to you it may be worth while. Sometimes it can be enough difference.  Generally when I see high temps like that on a card that new I first suspect a case airflow issue rather than a bad paste issue.  The thing isn’t particularly old. It’s possible I suppose that the paste was poorly applied or has dried out, but it doesn’t seem super likely to me.  The problem is if you’re hitting throttle numbers it may not be a maximum.  It might throttle a bit later but it would still throttle.

What of a 4 year old paste replaced with new one? Since on CPU's it does help, a lot.

Your GPU temps are fine at 70C, but if you want to repaste the GPU I wouldn't recommend liquid metal as its messy and can easily move from the gpu die and short something, and it can affect the surface of the heatsink.

4 years makes it more possible.  That would be a fairly early 5500x but I suppose it’s in range.  It likely won’t hurt unless you badly mess something up.  I just don’t know if it will help enough for you.  A judgement call.  If the paste is dried and cracked it could though. The thing with CPUs is they tend to be just a few degrees hotter than people like. Yours was over 10. You might get that though if you’ve got dried paste.

Liquid metal also has gallium in it which can react very badly with some kinds of metals. I don’t know what your ihs and cold plate are made out of, but that would need to be checked.  The 3 big problems with liquid metal as I understand it are application, conductivity and chemical reactivity. You need to take care about all three.

thing is, my R9 5900X ain't going over 75c under full load at full turbo. My GPU is toasty though. (pc specs in signature)

That’s the cpu.  Totally unrelated I thought. I didn’t think I mentioned the cpu.  Might be a typo or something.  GPUs have pretty close to the same system as CPUs.  The video card may not have an ihs on its gpu I suppose. Some do.  Most don’t.  I’ve never taken apart a 5500x so I don’t know. Silicon iirc is impervious to gallium, though things surrounding it may not be.  Generally chips without an ihs have different system with a rim around them which is made of metal and can have the same potential problems as an ihs.  They’re easier not to touch though.

it was extremely easy to teardown. I replaced its dried and cracked thermal paste with some Arctic MX4 I have in my drawer for CPUs. There is a small difference but I was wondering if I could see more difference with an even better paste like the cooler master mastergel pro or the THERMAL GRIZZLY KRYONAUT

even if the hotspot reaches 95-99 oC???

The Arctic MX4 did help a bit but I want more since buying something better is out of the picture for now

More is difficult.  Liquid metal transfers more heat than other paste type but has some severe problems and may not work at all for your application. It may give you another few degrees, but only that.  There are metals it reacts very badly with so you don’t have to just know what general metal is used but the actual formula.  Copper isn’t always 100% copper.  My memory is it will eat anything aluminum or anything copper, or something like that.  The issue is it has gallium in it, so your cooler can’t have a connecting plate that contains anything it will react with.  Also it’s electrically conductive and can short stuff. 
There is more powerful cooling perhaps as an option, (this would mean replacing the cooler on top) the problem there though is cards of that vintage and later are so tightly packed transistor wise that the problem can be less radiating the heat than getting it out of the GPU in the first place, and you’re already setting about maxing that one.

like an aftermarket cooler for the GPU? but that is a whole different can of worms that I don't even know if it is worth opening.
Maybe I will just wait for the GPU shortage to end and buy something more powerful instead of messing with my already valuable card
