Trying to decrease my 3070s heat

[NerdTryingToLern]

As its been getting hotter in my area having a space heater of a pc was starting to get a little annoying so I undervolted my gpu and tried to setup a custom fan curve and was just curious how does everything look and if I should make adjustments. I mainly do gaming and idle around 40-60c*depending on game* currently after my changes. I just want to be sure that the fan curve is decent since its my first time making one and I don't want any issues overtime. I apologize if my questions seem dumb or insignificant but I just wanted to be sure since there are so many people with more knowledge then me

 

 

 

Thank you for reading!

*laughs in 550W RTX 4090* RTX 3070 as a space heater... pfff

 

To provide actual help now.

 

Unless you're lowering the power target and potentially reducing performance, after doing an undervolt and such, you're kind of at the limit. The other mechanism is to limit the framerate in some games to reduce the TDP of your GPU.

 

Ultimately energy in = energy out, so unless you're reducing the actual power limit after making it 'more efficient' with an undervolt, then you'll still be drawing +220W as an example. You might be able to get away with 90% TDP and/or lower the temp limit which'll simply prevent the GPU from boosting.

 

The lower temperature really just limits the temperature delta and may make the GPU more efficient at the lower resistance (therefore can operate at a lower voltage), otherwise if it starts to get REALLY hot, you might throttle extremely hard if you're not allowing a sufficient temperature delta.

 

Q = mc|T-T|, m= volumetric flow rate, c= specific heat capacity, |T-T| being the absolute difference in temperature between the sink and source. Other thermodynamics equations work better in this scenario, but this ones simple and works well enough. The hotter the air is in your environment, the higher your fan speeds will be if you're maintaining a low source temperature to maintain. Might be a self-correcting feedback loop in your case if your goal is to reduce thermal output though.

Big word hurt head.... Anyways lol Ill definitely try out your recommendations and the fan curve probaly should be fine since my pc isnt getting to hot im just sensitive. anyways as long as im not playing rust on max graphics or something along those lines i should stay in the around 30ish idle and 40ish c when on games, which is fine

if you wanna lower the ambient heat output then lower the power limit, if you just wanna lower temps then turn up the fans. I dont feel the gpu as long as they are under 300w, above that they turn into space heaters for me, and 400w+ just feels awful

[NerdTryingToLern]

So continue to lower the voltage on afterburner or a similar program?

An airflow orientated case does wonders..

 

What case do you have now?

I believe its a corsair 4000-5000d series

What make + model RTX 3070 do you have?

Most new graphics cards (i.e. GTX 1000 series and up?) now have a "0 RPM" or "0 dB" mode, where the cooling fans are OFF, until it hits ~60*C.

That is the default fan profile.

 

Idle temperatures, even at 60*C doesn't mean much.

Whare are you under load (i.e. while gaming) temperatures?

 

43*C is considered COOL for a graphics card....

Up until 80*C ~ 85*C is still considered cool/warm, under load (i.e. benchmark test, gaming).

Anything above that, then you want to pay attention.

I have a nvidia geforce rtx 3070 im idling at 36c and when playing games like val i hit around 43c and rust around 50c its fine  for me it just gets a little toasty in my room most of all I just wanted to make sure my fan curve was set up properly

Make + model... as in... examples:

• EVGA RTX 3070 FTW Ultra?
• ASUS StriX RTX 3070 OC?
• Gigabyte RTX 3070 Aorus Master OC?

50*C is really cool for a graphics card.

Tune the fan speed to get the temperature + fan speed + fan noise that you are OK with.

 

If your room gets too warm, that is more of a room air circulation / ventilation problem.

NVIDIA GeForce RTX 3070 8GB GDDR6 PCI Yeah I think i did majority of what I can pc wise for the temperature ill just have to get some blinds for my window ect

So you have a Founder's Edition / Reference RTX 3070?
