Rate my liquid metal job...

[Morgoth]

i wonder if im doing it correctly... so you decide...
tempretures.. wel they are worse then i started with... thermal trotels immediately after firing up furmark...
tough idle is 31c...

Hi,
Looks lumpy which means lots of air trapped or just to much in those spots.

Might add a poll 1 through 5 ?

@Morgoth
Perhaps your thermal pads are too thick, or you didn't fasten the waterblock tightly enough

air traps is that a thing???

perhapds the thermal pads are the issue. the screws are realy fight but the ones of the back bracked im not sure how mutch force i need to aply there i assume the spring tension is enough or would i need to bolt it all te way against the pcb???

bro you turn screws till they stop. this sounds like a seating problem.

 

[cvaldes]

That would explain the immediate thermal throttling: insufficient contact between the heatsink and the GPU's surface.

you sure to screw these all the way until the metal of the bracket touches the pcb???

Hi,
When you delid a chip the preset cooler tension is off the height of the top of the chip
So you might should add some washers to account for the missing top of the chip now.

I personally don't use springs anymore.

wel my gpu never had IHS on it its direct contact with the package

Hi,
lol yeah I only looked at the lm job not what it was on

Yes, there are rubbery cushions on the middle square shape of the bracket (still there?)
Metal won't touch the pcb unless where the screws are located.

Don't fasten each screw fully at once, as it can push the liquid metal spread unevenly. Fasten a bit, move on to the screw on the opposite side (skip the neighboring screw) ... After all 4, get back to first screw and fasten more.

Ah, looks like you were trampolining the block over the gpu die.

That spill over is scary

That spill over is scary

he's fine he coated what he needs too (red)

 

[xtreemchaos]

that looks quite good coverage, dont think id do any better prob a bit worse to be truthful. well done.

 

[ThrashZone]

Hi,
I'd just drag the puddles to the middle and call it a day.

When I first applied liquid metal to my 1080ti I used a too thin coating and the temps were worse than they had been with regular TIM. I had to add more liquid metal to get the temps correct.

The footprint left on the heatsink makes it look to me like a perfect application -- much better than my initial attempt.

The temps are the real proof though, they should be noticeably better.

 

[Morgoth]

so i toke it appart removed some thermal pads where they should't be
added some more liquid metal
and tighted down the screws of the brackets all the way
temps are beter but the darn hotspot 105c is still there...
cant even last a minute in a game with out shutting down...

 

[Shrek]

Given that even a mediocre thermal paste will only drop a few degrees, the best a perfect thermal paste can do is get those few degrees back.

 

[xtreemchaos]

vegas are hot mate, that hotspot is within range just, whats your die temps now ?.

tough opening war thunder forces it to thermal shut down

Hi,
Put a 0.05mm thermal pad down tighten everything up see how much of an impression is made.

Only way to lower a cooler like this is to shave the stands

 

[xtreemchaos]

ah somethings not right, id try adding a tad more LM.

 

[Morgoth]

i allready did on the second time how mutch more do i need to add? entire 1 gram?? i readed thats enough for 10 aplications??? just yolo it??

im going to mesure the high of those standarts and the hight of the silica protection thing around the die so how mutch off it is

 

[xtreemchaos]

i think Thrashzones thinking along the right lines, i carnt remember what my vega64 hotspot was rel to die temp i think it was something like 20c higher darn memory its like the tide.

 

[Morgoth]

btw grey thermal pads i use are 1mm thick and they have imprints on it. the green ones are 3mm thick
