3080Ti Temps question

[Benji64]

So i profess to not being the most savvy with the ins and outs of cards. However

 

I have a 3080ti watercooled GPU that i got made for me (as i would mess something up making it myself) and the temps on the card seem off but it might be me.

 

The card is sitting at 27c - 31c idle which is no drama. However when gaming i am seeing the following temps

 

GPU - 85 - 90c

Memory junction temp - 68c

Hotspot temp - 105c

 

Now the place i got it from (wont name and shame) has had it back, And reaplied thermal and changed pads etc and have said it is fine. But it still seems warm to me, My previous air cooled 1080TI was getting temps of around 75 - 80c max with a smaller case and worse cooling. 

 

Is it just that the card is running hot? Or is it that the hotspot and gpu temp are not as important as the memory temp and i am overreacting? 

I just want to be able to play things after work without worrying that it might just die on me sometime. 

 

I take the side off and air blow out and dust roughly every 2 weeks so i dont think its that.

 

Thanks for any info and help you could provide.

If you haven't played with OC/power limits... there's definitely something wrong with that card unless you live in a tropical area with 100F+ room temperatures. Those temps would be pretty bad with an air cooler, let alone the liquid cooling you have with yours.

Hmmm there's something worng

My watercooled 3080 (done by myself so with very low skill lol), no OC (basic Eagle card don't go over 1900MHz)  is max GPU 65C/ Hotspot 80C/ mem junction 85C, after hours of gameplay and with low speed (40%) silent fans on a 360 rad

I can imagine an overclocked 3080Ti can get maybe 10-15C warmer, but still your GPU and hotspot temps are way too high

Something isn't working properly in your loop, pump problem or bad contact to the chip

Hotspot is likely reporting the memory (the mem gets super hot on 3080 and higher cards), I would definitely look at fam curves on the rad because it sounds like it's in a silence optimized curve which is terrible for thermals. Could also be a bad mount or TIM application. 

I would check the pump first because those temps even passively cooled with water using just convection seem high.

I havent played with anything. And im in the UK so definatley not high room temps haha. 

 

I've spoken to the place that built it and they seem to think its all fine. But it's got me worried that its not good for the card. I don't really know what to do to be honest. 

I am trying to get them to explain what they fixed when they took it back but it seems they just redid the thermal paste.

Yeah. I'm just going to have to keep badgering the supplier until they sort it i think. I imagine they've skimped somewhere, But the pump appears to be fine from what i can tell. I really wish i was more technical but i just enjoy gaming but am not that great at all the ins and outs. I just want to be able to play some warhammer or FFXIV and not worry about the PC dieing. (Yes, Im that kind of person haha)

 

The thing i find strangest is the disconnect between the memory junction and gpu/hotspot temp readings. My friend is more knowledgeable than me so i might get him to open it and take a look. 

 

Just the hassle of sending it back and forth to the supplier is a pain and of course riskes damage each time.

Don't think so, it's hotspot *on the GPU chip* and mem temp is another sensor (on the vram chips)

Some 3080s have bad mem temps because on some designs chips were on the reverse side of the card and they were not or badly padded, and with poor plastic backplates..That was the case of my Eagle and first thing I did before watercooling it was to add/replace those, for -15C mem temp
