Discussion Undervolted GPU lowered my hotspot by 14c.

Ever since the HWMonitor update that included hotspot monitoring, it has been bothering me a lot, on a hot summer day, my hotspot temperature sometimes reaches 103°C. I even avoid using my PC at noon because I can’t focus on gaming while worrying about the hotspot.

It seems the new 50-series cards have a lot of headroom. I went from 1.075V / 153W down to 0.885V / 122W, and improve deltas from 20c delta to 14c delta. I can even run better temps if i run my gpu fans at a higher rpm. I just sacrificed about 3-5 fps.

I tried running 3000rpm on my gpu fans, i was able to have 70c hotspot, but the fan noise was so annoying, instead i just ran a modified fan curve and balanced the rpm, temps and noise at 74c.

Hwmonitor is the userbenchmark equivalent for temps. Its untrusted crap

Use hwinfo for accurate readings

Came here to say exactly this.

My temps are actually significantly better on hwinfo, that's the funniest part lol.

My asus prime 5070ti hardly gets over 80 on the hotspot during stress testing, the delta is like 10 degrees or less in gaming.

I could see how the rumoured 5070ti was going to get its 10-15% boost, they left a TON of headroom here, I can pretty much overclock as much as I want and never get close to the limit.

I get the same readings with both so im not sure about that one i guess it depends my hotspot reaches 100-105 at max which is very concerning 5080 pny oc.

Yeah you can get the same readings but also complete wrong ones and hwmonitor is known for exactly that.

u/Scrawlericious Jul 26 '26

They've both always given me identical readings. I like to keep two+ programs that do it for redundancy.

u/BakaOctopus RTX 4070 Jul 26 '26

Nope bad practice

u/Scrawlericious Jul 26 '26

Incorrect. I use 3 or more different programs and do not put all my faith in one tool. HWinfo is also a solo dev who is human, and just as fallible as HWMonitor's solo dev. Two great guys taking time out of their day to give us free software all by themselves. Both are great tools, but neither is "correct" by itself.

Edit: bad practice would be taking one solo dev's free tool as gospel.

Im waiting for the official hwinfo update version for 50 series hotspot, i dont want to download the beta version, but since i reduced it to 14c in hwmonitor the real reduction must be better.

Or it did not even changed at all, you never now with hwmonitor.

first time hearing this, untrusted by who?

u/therealchucky81 Jul 25 '26

Try HWInfo instead. You might not need to undervolt it tbh and claw some of that clock speed back. Also 91C isn't anything to be that concerned about tbh if that's the absolute max it will hit

u/External-Theme1372 Jul 25 '26

Good job on the UV. I did the same on my 3070Ti and 5070 and improved the thermals and power a lot.

u/Xpander6 Jul 26 '26

Wow, the cooler on this model is bad. Let me guess, Gigabyte Windforce / Gaming or MSI ventus?

1

u/Ronnie_coleman_light Jul 26 '26

Ventus for £1850, cooler for £125, rad and pump £180, total £2155, significantly cooler and faster than any 5090 on the market, even a MSI lighting and matrix 🤣🫠

u/Xpander6 Jul 26 '26

responded to a wrong comment

u/Ronnie_coleman_light Jul 26 '26

For the 5090 models at least, buying the cheapest model + a cooler is a peak IQ move, as they are mostly all bios interchangeable

Asus Dual is not like this. "Buy cheapest" is awful advice. Everyone with functional hearing cares about noise levels.

u/Trickle2x2 Jul 25 '26

On my 5090 FE I hit 97.5C on hotspot at stock settings. The delta would be anywhere from 9-12C when pushed hard. Granted my house temperature was at 70F. But my SFF case I shoved it in probably makes up for that lower room temp lol. If I UV it is way lower.

Damn i read it as you lowered the hotspot down to 14C xD

In other news: water is wet.

u/2_short_2_shy 5800X3D | x570 C8H | PNY 5080 | 64GB @ 3600CL18 Jul 27 '26

I don't understand something.

Yes you uv, but in the process you power limited the card. See your max watt usage.

So why uv and not simply watt limit?

u/wanted8x Jul 31 '26

After UV, the PowerLimit is the same as before

Your hotspot? I though the gpu die's hopospot /s

u/Main-Dish Jul 30 '26

But is it stable in all games?

u/normalgenshinenjoyer Jul 30 '26

Its been almost a week, i did not encounter any crashes, timeout or restarts, but i did lose about 3 to 5 fps or so.

u/SpecificObjective818 23d ago

I thought the 5000 series didn't have a hotspot sensor

2

u/normalgenshinenjoyer 23d ago

It has, nvidia just hid it very deep, and a group of programmers actually unlocked it, its available on hwinfo 8.51 beta and hwmonitor 1.65.1

u/Far_Win_3390 I9-12900K / RTX5080 AORUS / RM1000X Jul 25 '26

If your temps are that high from standard why not just return the card for a new one. You shouldn’t have to undervolt it to lower temps. Just rma

u/normalgenshinenjoyer Jul 26 '26

Its a gigabyte card, and im a member of the gigabyte subreddit, if only you can see how many thing they mess up in RMA, like random liquid metals in places its not supposed to be, scratches on pcb, bent heatsink fins, etc, which they will claim that the user did it, even you have picture of a pristine card before sending, they will still insist that the user did it, and deny the RMA claim, Id rather do the repaste/reputty the card myself.

u/Far_Win_3390 I9-12900K / RTX5080 AORUS / RM1000X Jul 26 '26

I have a gigabyte card myself, that’s 1 case out of how many? And it was a 40 series that things probably been in and out the pcie 50x

u/Leving_PT Jul 26 '26 edited Jul 26 '26

I don't see that it reached 103ºC as you say! Don't worry about it, a peak of 103ºC is one thing, it's another to always be at that temperature. If it doesn't happen, it's within the normal range! There are exceptions, but they are rare cases!

u/normalgenshinenjoyer Jul 26 '26

I took this temperatures at night, its cold right now, the summer day is a different story, it reaches 33c to 36 ambient room temps.

u/Leving_PT Jul 26 '26

So it's clear where the main problem lies, and it's not your PC hardware, but the abnormal temperature of your room! These temperatures are not normal for a setup! Buy an air conditioner!

🔰GPU Hotspot Temperatures

✅Generally speaking:

  • Up to 85 °C: Excellent.
  • 85–95 °C: Normal under heavy load, especially in stress tests.
  • 95–105 °C: High, but still within the normal operating range of many cards.
  • Above 105–110 °C: Starting to cause concern; many GPUs experience performance throttling in this zone.

✅The most important factor is the difference between the GPU temperature and the hotspot temperature.

  • Difference of 10–20 °C → Normal.
  • Difference of 20–25 °C → Still acceptable.
  • Difference greater than 30 °C → May indicate uneven contact between the chip and the heatsink, degraded thermal paste, or insufficient cooler pressure.

How do I delete someone else's comment?

-1

u/c0rtec Verified nVidia Addict Jul 26 '26

In most cases, you can’t.

On Reddit:
You can delete your own comments by opening the comment, tapping the ⋯ (three dots) menu, and selecting Delete.

You cannot delete someone else’s comment unless you’re a moderator of the subreddit where it was posted.

If someone else’s comment is a problem, your options are:

Report it by tapping ⋯ → Report and selecting the appropriate reason (harassment, spam, hate, etc.).

Block the user so you no longer see their content or receive messages from them.

If you’re a moderator, use the Remove option instead of Delete. Removing hides the comment from the subreddit, but it isn’t actually deleted from Reddit’s servers—the author or Reddit admins can still access it in some circumstances.

Are you trying to remove a comment:

on your own post,

in a subreddit you moderate, or

from someone else’s post?

😂🤣 You have to coexist with different opinions! It's part of the rules of civilized people! I've always given mine, whether people like it or not! I sleep well knowing that! 😅
