Rtx3090 temps on block

Hi , looking for some feedback on my gpu temps
I installed a bytski full block with active backplate on a gigabyte rtx3090 gaming oc

Really happy with the memory t junction tems (48 under load) gpu overall temps sit at around 68 at load which again is not bad , but the gpu hotspot has bwtween a 15 and up to 20 delta vs the gpu temp, so if gpu is showing 65 the gpu hot spot is about 83 to 85.

Im pretty happy as quiet running is what im after, but was wondering if the delta was to much and perhaps the gpu hotzpot is a little high ? Perhaps not enough contact with the plate ?
 
I have a 3080, but I think the delta is meant to be 10c territory typical if mounted well. It does suggest that perhaps there is a bad bit of contact somewhere.

Might be worth re doing if someone confirms if any throttling might occur.

Tempted to do mine. Im mining on mine and with a mining underclock my ram is running 96-100.
 
as above 68 core temp is on the hot side for a water cooled card .. what is your water temp at when the gpu is at 68 deg ? Hotspot does seem on the high side ( should be >10deg) but your vram is really low so i would say some contact issue possibly the thermal pads not allowing the die to make full contact with the cooler. would 100% disassemble and investigate :)
 
Thanks both, i reseated and the hotest the gpu reading i got (playing ascent maxed out @ 4k) was 57 degrees though hotspot delta is still there but5 degrees less of a gap (15 degrees higher) this is much better , note the bloody mb i have does not have a sensor header ! So am in the dark about liquid temps ( need to do something about that) , but had the rad fans quit low, almost silent, whilst it might not be ultra cool im happy with this (memory junction was 53 during the above and cpu max was 54. For silent opetation im good (i also suspect that as it has the active backplatecvcooling temps will be a bit higher).
Fyi
2x aplhacool 360mm (30mm depth) with sl120 fans running at 1020rpm

Oh and gpu had 100mhz overclock , gpu memory 650mhz overclock with undervolt of 90%.
As i say this isnt chilly but feels like nice temps in terms of keeping my hardware in safe parameters whislt enjpying silent gaming at 4k ?

Was gonna say your temps are way too high, a good mounted block should be in the mid to high 40’s tbh on a minimum 360 radiator. I’ve never had a gpu go over 50c at the core. Memory temps can vary depending on the block and thermal contact between the pad and the block. Theres a lot of variables at play.
 


Thats after running port royal loop for about an hr.
Temps are CPU, GPU, GPU Mem Junction, GPU hotspot.
For an RTX3090 , i think this is ok

My hotspot temp is about 20C higher than the core temp, which seems to be fairly normal. It's not something I ever look at or worry about.
 
my 3090 fe was running in the 55-60 degree mark under water and under volted to 85% power (296w) so i took the card out, cleaned the block and re-mounted and afterwards my temps are 47-53 degrees but at 114% power target (395w), the clean and re-mount have done wonders for my card i can happliy sit at 2100mhz core clock in games at the above temps and remain very quiet thanks to my dual 420mm rads and d5 pump/res combo, hot spot in in the upper 60's which is totally fine too
 
Then why TF are you asking? It's obvious that it is.

I was asking about delta's, got good advice about reseating, did so got better result, posted result with 15% delta to see if that was common.ehich others have subsequently commented on.
But really appriciate you invaluable input.........

Reverse movement, close to ground towards soild substance, descend & remain.
 
My delta is bad gpu needs a reseat

I get 40c over water when really pushing the gpu and then another 30c over that on hotspot

At full load: gpu 64c, hotspot 92c, water 27c
 
On air with a repasted and padded 3090 Fe I get the following absolute maximums at 400w
Core : 67
Hotspot: 79
Mem junction: 92

Your temps seem pretty bad Grim. Definitely try re seating the block. Delta for GPU to hotspot should usually be between 10c and 15c for a good mount.

Way to hot considering your water temp , i imagine the die is having very little contact with the block due to the big delta difference and the high hot spot temp ... get it stripped down and find out what's stopping it making contact . You have the same card as me if i remember correctly which is a 3090 strix oc ? my temps are below apart from hotspot which is 10 deg above gpu temp, i am using liquid metal between die and block and gelid ultimate pads for all thermal pads .

What block are you using? I have a pair of the same cards and will be using EK Vector Strix blocks with the active backplates using the same pads and liquid metal. The gelid ultimate pads are harder than the EK stock pads whats the best way to ensure good contact?

That's with water block ? The vram temp seems high, I get 80-84c while mining stock cooler with 1.5m ultimate gelid pads fans at 60% 220watts 101mhs

I think that's a old post, before I did anything.

I hit 68 when mining with watercooling with a silent profile. It I turn the fans on and up the pump speed I think it's more like 60c. Takes a long time to see changes with watercooling, but it's roughly that.

gotcha got me confused :cry:

I am using the EK Vector Strix block with EK active backplate. as for the pads i just used the same sizes as EK state to use which is a mixture of 1mm, 1.5mm and 2mm so to do the card properly cost a bit as you have to buy 3 different sizes and a few packs of each to have enough for 1 card let alone 2 ... the pads are harder but had no issue with getting the blocks sandwich together , well no more than if trying with the ek pads ... its bloody tight but does 100% fit :D
