Anyone replaced Tim on 480 devil?

Just a thought really, I'm gonna delid my cpu at the weekend and bought a gram of thermal grizzly.
I'm notorious for loosing tubes of Tim, so I thought I might reseat the gpu cooler at the same time..

Is the stock paste decent? Or does it use pads? Basically would it be a waste of time doing this.

Cheers.
 
Well I think I'll have to now. Haha! I'm curious.

The max temperature I've seen on the gpu is 83c according to hw monitor. Bizarrely that was playing arkham city.

My other current game of choice is witcher 3 but that does not seem to push it over 80c.

That said we are coming into spring so ambient air temperature is higher. Most of my baselines were done January to March when air temperature was cooler, as it's a new build so I'll have to take that into account.

Is it just the main gpu chip that has contact with the cooler? I'll look it up but of anyone knows it's appreciated.
 
Strangely the gpu fans are fairly quiet, but it does run warm, but i don't really want to boost fan speed if I don't need to.

Mainly my cpu fan is annoying.. And my exhaust fan, but I think that's more down to vibration /reverberation, so I might look at putting some blu-tak or rubber grommets on the screws and mounts at the same time.

Thermal grizzly kyronaught knocked a good 5 degrees of my max temps with same fan speed on my 980ti amp extreme. Did nothing for idle temps though.

Id guess the thermal grizzly liquid metal stuff would be even better. But thats more risky.

Thermal Grizzly conduct<what ever> is the liquid metal and pretty easy and safer to use than CLU

My personal experience was with the kryonaut (normal paste), against the EK Ectotherm and the paste MSI is using on the GTX1080.
On watercooling, the Kryonaut dropped my temps a good 13C under load and 10C idle, against Ectotherm which is similar to MX4, with max overclock 2190.
While on air, i was able to OC with Kryonaut all way to 2084 and keep it stable, while with the MSI Tim couldn't do more than 2048.

Nice :) also i wouldnt say any liquid metal is safer than another lol. And i thought clu was easier to spread tha clp and thermal grizzly conduct-...naught what ever was about same as the coolabs pro. In terms of application.
 
Yeh I've never liked the idea of highly conducive Tim! Hence the kryonought. Accidents happen!

I don't really care about idle temps as long as they are below 50c.

TG conduct is safer because it doesn't melt solder found on some cards, since is not Gallium based.

good job there is no solder on the die then haha. No but seriously if Liquid metal hits any transistor that's around the die its going to do damage regardless if it eats solder or not. Or any other part of the PCB or motherboard PCB. If its powered on ofc but you would clean it off if it wasn't powered on anyway. I still wouldn't consider it safer. If its going to damage your card its not because it eats solder or melt solder lol.
 
Also change any GPU with decent Paste, and if it's my own some updated thermal pads. Most are 4-5w/km or what ever the unit it, Alphacool goes up to 7 but i tend to slap on 14/17 rated on VRMs
 
My paste didn't arrive on Friday, so I've not been able to do it yet.
That said I found some pics of the devil with the heat sink removed there's quite a few thermal pads under there to.

so was wondering whether I should try to reuse them or order some pad to replace them with.
I don't know much about the pads, I suppose getting the right thickness is important, they seem to come in difficult thickness depending on how big the gap is?

Here's a pic for reference http://www.overclockersclub.com/reviews/powercolor_red_devil_rx_480/#&gid=1&pid=93696

Also I updated my mobo bios on Friday and upped my cpu to 4.8 and changed some fan settings so I'm gonna have to record some new idle and load readings for a comparison.

I've also found some copper shims online that you can use with paste in lieu of pads so I'm wondering about buying some of them instead.

I think I'm gonna have to take off the heatsink and see if I can measure the thickness of the pads so it's gonna be the weekend before I can realistically get some before and after figures.
 
Reason I'm thinking copper shim is that the pads I saw have Wmk 8, where as the copper shims are Wmk up to 140, so I'd guess even with a bit of thermal paste on them to hold them in place they should outperform the pads?
I guess I'll have to be very careful about thickness though to get good contact as they won't squish down like a pad will for good contact.

Anyone used shims before? Any tips?
 
Yeh I am probably over thinking, if the pads don't get torn up when I pull the heatsink, I'll just leave them be.

Paste arrived so I might do it this evening.
 
OK ive got some before figures:
[email protected] 1.375volts

cpu idle temp 30c
rx480 idle temp 50c

TIM on the cpu is standard coolermaster tim as supplied with the heatsink.

max load temps after running

cinebench
3dmark
heaven
realbench

cpu 82c
gpu 79c
