Should I be concerned with my GPU hotspot temp?

Playing some PGA 2K25 recently with full maxed settings and 150% render scale and I noticed my GPU hotspot temperature was reaching 90c. GPU temperature seems to be in acceptable levels of around 72-75c. Is this hotspot temperature concerning? The GPU is a 4070ti Super, purchased about 6 months ago. Is it worth repasting?

You could try an undervolt.. I done this on my 4070ti super and my temps max out around mid 50s and jot really any noticeable drop in frames / performance.

Yes undervolt to fix cooling issues...don't fix the problem just tackle the symptoms..

I don’t understand this comment.

Heat is the product of energy.

Excess energy = excess heat.

Less energy (undervolting) = less heat.

Undervolting is a therefore a very good way to curb excessive heat.

If anything, alternative cooling solutions (fans, heat pipes etc.) would be treating the ‘symptom’.

Appreciate the responses, thanks

I actually forgot about undervolting and I don't think I've ever done it before. I'll have to take the time to watch some YouTube videos and follow along. I can't imagine it being too difficult. What's a surefire way to make sure the card is stable and running properly after completing the undervolt?

Cheers
 
Honestly that seems an acceptable delta for the hotspot. 10-15 degree delta is good. 15-20 is acceptable and then 20+ normally means your paste has pumped out and needs replacing.

I'd keep an eye on it and if the delta increases then repaste or send it back if you are within warranty.

I never done it before either, I followed a guide on YouTube on how to do it through MSI afterburner, very quick and simple..not only did the temps plummet, but the fans never go above 30% when they do “kick in”.

I used a YouTube video to undervolted my 6950xt. It was pretty quick and easy, so give it a go.

My temps dropped by about 30c, and electricity use by about 100watts! No real difference in performance, either.

That's not a fantastic hotspot temperature, but it's not an actually bad one, either. It's fine. If it drifts upwards from there over time, do a re-paste. Otherwise, leave it be.
 
The Hotspot temperature is measuring the hottest point of the whole card, not just the GPU die, if your GPU is reading 75c that's probably the hottest part of the die, 88c there is probably your power stages, your VRMs.

Repasting is not going to make this better, if anything it will make it worse if you're reusing the original thermal pads on the VRMs.

It is warmer than i would like, 75c with a 50% fan speed, i don't know which card you have but its cooler while NOT at all problematic is not great, could be better.
 
90°c is fine, not cool but neither unacceptable. 10°c lower following the undervolt is much better of course!

Need to get around to doing this on my 5080, temps are great (with the catch of no reported hotspot anymore), but I'm curious to see what drop in wattage I can achieve without performance degradation.
 
I have a 3090 Suprim X and when playing New World the hotspot is hitting 105c.
Does undervolting this card make a difference, or do they need pads to be replaced?
I don't u destiny if undervolting doesn't cause any drop in performance, why they don't get software to do this?

MSI afterburner is software that is doing this for you.

Yes - undervolting will help.

Thermal pads on the 30 series were pretty dire, so replacing those would also help.

Here’s a vid for the undervolting.

since when? ive always seen it referred to here as the highest spot on the core never over the entire card

I got that from AI, further investigation says you're right, tho its an AMD article it should be the same for Nvidia, 15c - 20c Hotspot delta is considered normal, anything much more than 20c, 25c or 30c is not.
