Rate my liquid metal job...

[xtreemchaos]

i like factory fitted blocks just for the simple no fuss just fit, my 2080 is one and its never missed a beat. but dont give up with that block yet there has to be a fix.

 

[ThrashZone]

EK water blocks always send plastic washers to add as well.

I general no one does LM and water cooling, as it is plain stupid and useless. Thermal dyinamic is differs from air cooling when you need a fast transfer, with liquid it is not needed, you can use basically any compound and they all will perfrom within margin off error.

So wipe that off and put some normal paste and don't blame china water block, no other block will offer you something more yet it be Alphacool or EK.

i had mx-5 and thermal grizzly kryonaut extreme on it.. both the same results
btw acording to the orginal manual i shouldt be using the back bracket and the orginale screws that came with it are way to short
after reading several forems its all pain in the ass with this block

If you screw evenly the card to piece thick metal why on earth it would bend and need that bracket? How it would bend if the block ensures a rigid structure and is screwed across all card surface?

You put everything on, put the screws and gently tighten it till they stop. Those blocks are fool proof. They don't need any springs whatsoever.

Your are putting more pads where they should not be,

Hi,
On a gpu maybe not but cpu's it's not unusual to water cool and use LM.
Water on a gpu with good paste will normally cut the thermals in half I know mine have usually maxed 60c with very heavy usuage compared to stock air coolers.

*why on earth it would bend and need that bracket? * WEL I DONT KNOW MYBE ASK SAPPHIRE?? why did they even add it? MUST be there for a reason? IST IT NOT?
reason i put pads where they should be cus i cant find where the god damn hotspot is located... i toke the thing now 20 times apart!

I have tried for myself, it gave zero improvement when doing loop. All that matters is your loop temperature and heat capacity of your head/block. If you have different results, you do something wrong.

VEGA is a different animal. If it is water cooled, that bitch will consume even more power as it didn't hit the temperature as it did on air, basically it could look the same temperature wise, it will just clock higher and uses more current like a pig. You still will need to undervolt it.

Because you cramp it on a stock radiator, it hangs only to one place like CPU and then it needs that clamp as it bends the PCB, but if you cover the whole PCB it obviously cannot bend.

for my next one im planing to buy waterblock from wel know brand like alphacool.. not touching those chinese brands any more..
im also wondering if im beter of getting a prefit waterblock with gpu from sapphire instead and if i can use my existing tubes on it
if there not press fit on the block...

I think the hotspot is located in the GPU die. The temperature is the same as the core both 38c.

.

grey 1mm pad are from gilet
green ones are from kritical

so i did what you told me to do... i also found out that the screws i orginaly used are not threaded all the way (first 3 mm) so i could't screw them more in so the pcb didt touch the standoffs on some places so i did this for a fix to see if it works...
and after all that. nothing changed.. stil hot spot 105c and shuts off
i also used a flash light to look between the cold plate and the pcb the pads are toughing the 2 sufraces. and the GPU die also seems to be toughing the cold plate

also kinda starting to think to put back the air cooler on it...

Yes thermal pads looks better.

what realy troubles me that there is no offical mention from amd or sapphire where the hotspot is mesured. is it the mosfets? is it the hbm? the gpu die??? where??? drives me crazy

These chips now have dozens of temp sensors on die scattered all around it.

The "GPU Temperature" reading is the average value of a specific sensor on 1 edge of the die (value always from same sensor)
"GPU Hot Spot Temperature" is the average value of the hottest spot on die. Meaning this keeps tracking (switching report instantly) of the hottest reading sensor (of them all) and report the average value.

 

[xtreemchaos]

yes the hotspot is on the die near to the memory chips .
i manage to find a old gpz readout on a old hd

I believe has nothing to do with memory chips.

As I said the hot spot reading is switching sensors constantly to report the highest average value

EDIT:
You can read your own description (for your own GPU) on HWiNFO64 (enable tooltips)

Can you figure out how thick are the pads he uses... while he also uses furmark, that's pretty wild, I can bet the error lies with things he figured out he should apply and screwed up the mounting pressure.

 

[xtreemchaos]

i dont have a vega anymore that screen shot is prob from 2019/20, thats what sapphire told me where the hotspot is im not going to argue the point as im too old and like to use my time to good effect but you could allways email them and see if you get the same.

My estimation matches his statement. 3mm (green pads)

I dont like using furmark any more for some years now... Better to use something like Heaven4.0 or Superposition on extreme settings.

What I found odd is that the GPU shouldn't crash upon high hotspot temp. Normally it should've cutdown boost to control high hotspot temp. At least thats how my 5700XT reacts (at 110°C hotspot reading).
Exactly how CPUs are reacting upon max operating temp.

There's nothing wrong with the waterblock


Take all the thermalpads and try again. Your gpu die is not in contact with the block.
You used too much liquid metal and I suspect you didn't clean the die and block well before the job.

See how it goes without thermalpads. Specially remove all the thick ones.

I'm using the same brand of block and my temps max at 70 in summer, my room is not air-conditioned, ambient is 32 degrees and I'm on 4k.

Did you clean the waterblock? Can we see the other side.

 

[Morgoth]

hell im not using the 3mm pad any more. first reason i was using it becus the orginale ones didt made an imprint....
wtf has my radiator to do with brackets and backframes and pressure?? WTF

i prety mutch rubed the entire surface with the alcohol wipes it came with......

You use some whacky screws that supposedly ends the thread within the spacer and don't even tighten up the block. Ghetto it is... you apply ghetto where you shouldn't. Use bare card, look up some pics, there are some examples in Linus forums with exact the block.

And you think i didt try that the first time???

Yeah... but from the pics I see he has pads both on the card and the block where the chokes sit. It is a mishmash supposedly.

 

[Zach_01]

I think these are not on the same spot

 

[Ferrum Master]

I think these are not on the same spot

That's the issue... those are not needed in the first place IMHO, that could be the reason the block doesn't even touch the die properly as it stumbles on the chokes.
