Question RX 6750 XT hotspot temperature

[Lrgrasso]

Hello guys,

Just bought a MSI 6750 XT and I'm a little bit worried about the temperatures in the GPU.

First of all, let me clarify that the video card is working great, I have not experienced blue screens neither thermal throttling.

However, while in full load, the hotspot temperature is reaching over 100°C most of the time. The max temp I've seen was 112°C, while the GPU as a whole stays around 80°C.

Is it something I should be worried about ? Unfortunately I've not found any documentation regarding hotspot temperature, so I hope you guys can give some help in this matter.

Thank you!

what case are you using ?
is it brand new ?
and what is the exact make model msi 6750xt ?
a slight undervolt and adjusting the fan curve will help lower temps a bit

Thank you for the answer!

The case is a Galax Nebulosa with 3 exhaust fans and 2 intakes;
Yes, it's brand new, arrived on last monday. It is a MSI RX 6750 XT MECH 2X 12G;
I tried to adjust the fan curve but maybe did not do it very well. About undervolt, I would lose some performance, didn't want to do that since it's a recently bought GPU. Do you think that would be better to give up some fps to make the card works cooler ?

Fan curve likely doesn't do anything because of the finstack orientation of the Mech's cooler, which determines where the card exhausts its waste heat. That orientation does not work as well in the current case trend. The rear exhaust is fine, but the front exhaust is screwed against a front case intake.
Speculation on my part, is that this type of gpu cooler does better in a chimney case, or a case that has side panel ventilation and the front panel is sealed.
Ironic, or perhaps intentional, that this design isn't seen on the higher product tiers of any brand...


The gpu likely needs a repaste if you're seeing ~40C gap between those 2 values.
Do NOT even look at the thermal pads. They aren't related to the temperature gap, unless you bought the gpu 2nd hand and the previous owner replaced the old pads with incompatible ones.

you wouldn't think a brand new GPU would need a repaste. If it does, I would be more tempted to return it than "fix" a brand new card.

can't find a lot on that case, mostly sells on Amazon. Gabinette just means cabinet, Its not brand name.
I wonder which one it is - https://www.galax.com/tc/cooling-cases.html as they all look the same.
GX700 doesn't seem to be on there.

Yes, it is, indeed, a cheaper GPU with a simpler project. The case is a mini tower and the video card is very close to the bottom, the fans are just 3 cm from the floor. Could be it causing the overheat ?

It is a new card. I wonder if it came somehow damaged from the manufacturer. Thank you for the help!

Yes, absolutely. I planning to return the GPU and get a new one if can't figure out a solution. RMA to such a new card is a shame

My case is none of these. I think it is out of order. But looks lot a like those in this link, the difference is mine is a mini tower. The front panel has place to only two fans, too. Thank you for the help!

I misread Lgrasso's reply to ilukey77's questions. Didn't feel like going to sleep just yet.

This is the case, isn't it?

https://www.terabyteshop.com.br/produto/13931/gabinete-gamer-galax-nebulosa-mini-tower-vidro-temperado-sem-fan-black-sem-fonte-gx700

It is a new card.

If it was purchased through a 3rd party seller, it might not be.
I agree with Colif about returning it.

Yes, it is. Do you guys think could it be the problem ? I already contacted the seller to change the GPU for a new one.

Thank you for the answer.

3 exhaust fans is odd on an air cooled PC. Are all fans in PC the same size?

I don't think Case is likely cause.

I found a few 6750XT with scores up near 110 but thats max temp it should run at. Most of those cards run at 75 max. AMD cards seem to escape factories with high hotspot temps. Not all but enough of them. The reference 7900XTX had problems with that. mine at idle sits 3c above GPU temp.

The case looks fine to me, and you report the gpu core being around a healthy 80C.
I wouldn't go too high on gpu slot width in that case though, as axial fans need at least another PCI slot's worth of breathing room.

Yes, all 120 mm fans. The top and rear ones are exhausts and the two at the front panel, intakes.

I don't think Case is likely cause.

I was already planning to buy a NZXT mid tower.

Good to know. I will return it and get a new one. Thank you!

The GPU is ~1,5 cm apart from the case bottom (see image). Could it be a problem ?
Thank you.

112C seems very high, I concur with the others and I would either repaste the card or get a new one.

Thank you.

how much ventilation is there under the card? I mean, what does PSU shroud look like? I can see some Galax cases with lots of vents so it might be okay there.

it sure is close to bottom.

mine has more space

It could be a contributing factor to hotspot.
new case needs to have more clearance if you get one.

having more exhausts than intakes means its negative pressure, i wonder how much air is coming through front. Can you increase the speed of intake fans? it might help cool card. You could use something like https://github.com/Rem0o/FanControl.Releases

I wonder if you could mount a 3rd front fan and move one of the top exhausts there instead.

Frente: 2 x 120 ou 1 x 140mm
Superior: 2 x 120
Traseira: 1 x 120 mm

nope. Oh well.

 

[Lrgrasso]

Just an update: I tested the GPU in another case and the temperature droped 10°C, sitting around 95°C on the hotspost. It was expected from some reviews I wacthed, so think I found the problem.

Thanks everyone for the help!
