Max hot-spot temp for RTX4070

tugrul_SIMD · Jul 16, 2023

I have Msi ventus 2x oc version of 4070. By default and 35C ambient & poor air movement, it does reach100C hotspot temperature under 100% cuda load. Is this safe for this gpu?

Temporarily, I adjusted fan speed, voltage and frequency to make it cooler like 85C. But is the reduced fan-life better than running hot?

Please note that the card does not throttle at 100C hotspot temperature. This makes me think "maybe 100C does not reach other components of computer = safe".

The hotspot is always at 15C higher point than GPU. Dont know why. But downvolting makes thr difference 10 instead of 15.

Edit: ambient 40C now...

More concerning is that three DrMos have no cooling at all.

The fans look like they can be hot swapped and replaced easily if sold separately.

Undervolting alone should give you around 120 watts total power 2600 Mhz 900mV no need to adjust the fans.

40 C ambient is the one in the room right or in the computer. Where is that on the equator?

40C ambient on street. Its like 37C in room. Its the air coming from africa by just luck of wind in turkey.

Yeah, hotspot reaches 100C in 2 seconds, this shows the lack of cooling contact.

40c ambient is pretty warm. Without AC not much you can do other than blow more air around.

Invest in an air-conditioning unit. One of the best investments you could make for your home comfort. It roughly costs half of that RTX4070 ...

My 4070 Asus Dual drops about 30-40W with undervolt, i use 0.95V at 2700+ Mhz. You could also limit the power to 80% or around that value for lower temps without more noise.

Yes, air conditioning is in plans but not this year...

Then that's an indication that cooler contact is not really an issue, and it's just a combination of very high ambient + mediocre cooler + maybe mediocre airflow. Normal hotspot temperature generally is between 5-20C above edge temp, maybe up to 25C if we're being generous.

On some cards the hotspot delta is pretty much constant, on other cards the gap gets bigger with more power draw.

edit: but yes, hotspot at 100C within 2 seconds does show that a repaste and remount might be in order. Edge temps might improve as well.

Dammit.. Zotac using bad components

I will be sure to register for warranty :laugh:

Edit:

Scratch that.. bad cooling.. whatever I will do what I have to
