Quick question, I went from the VC on the left and just installed the VC on the right. While running a SLI stress test I noticed one GPU was at 79c and the other was at 87c. What might cause this? I cleaned and added new paste, pad all positioned correctly. Idle they are both even at 32c

Sorry forgot the add the photos. I am basically just testing the different versions to see which one is better

Have you check the thermal pads?

 

Yes I did reuse some of the pads, the 3mm or thicker ones due to me not having any but the rest were replaced and placed properly. I'll let the thermal paste set and if it's still very uneven I'll pull it a part and recheck everything

I forgot which one but there is a pic posted by @Prema on the thermal pad sizing

@D2 Ultima

 

These are the ones I used

Anyone use hwinfo? I'm trying to figure out what GPU I need to mess with, what one is the master and what one is the slave? GPU 0 or 1? Thanks for any help

Your master is the one that shows a non-zero % usage at desktop, and clocks up and gets hot if you turn SLI off and run a game/bench. I think theres a checkbox option somewhere to swap gpu order if gpu1 is master.

 

Lol why did I not think of that lol

So I think the thermal pads I have suck... Or I'm just retarded... Either way I need to order all new pads. After replacing all the pads my gpus temps sky rocketed. The brand I got was phobya off Amazon. They are stiff pads unlike the ones I had on there. Anyone have some pads they recommend?

So the GPU is idleing fine but as soon as I click on a program it jumps to 70+... I didn't see any issues with the pad placement or sizes and the paste looked good too...

 

I use the Arctic 6.0 W/mK 145x145mm pads off Amazon (you only use like 1/3 of them for a full install), I get 0.5mm and 1.0mm, using Mr. Fox's thermal pad guide image as a reference (sorry can't find that post atm) but I use 1.0mm in place of the 0.5mm in some spots due to heatsink being deformed and raised in the middle. They come in a resealable plastic bag with more plastic that you peel off on both sides after cutting it so I peel 1 side, place them, and then remove the other side's plastic after I have it all placed and pushed down to stick. Haven't had much luck with the 3.0mm pads, best I could find on Amazon was the SPHINX blue (3.2 W/mK)

I'm not really sure the 10x more expensive Fujipoly is worth it.

I think the screw in tabs around the gpus are worthless at least on my vapor chamber heatsink, they appear to be too loose to apply any more pressure, you might need a copper shim for your GPU if you have the same problems I do. I'd check your thermal pad pressure spots and paste spread on the heatsink after heating GPUs up to ~80C in AIDA64 and see what needs fixing.

 

Are those firm pads or are they squishy?

Sent from my XT1585 using Tapatalk

 

I'd say medium-firm, similar to stock 0.5mm pads, definitely not squishy like the 3.0mm stock pads. I haven't tried much other thermal pads so not much to reference against.

 

A slight give is fine, I used the black phobya pads in the past.

 

I can't figure it out then, I ordered new pads. I'm going to put the new pads in again and repaste it and if that doesn't work, I'll go back to my old VC

Sent from my XT1585 using Tapatalk

 

What's your current contact pattern like when you take the heatsink off?

 

For the pads? I followed this guide. All new pads except the 3mm because I didn't have any and they were fine. Most show small indentions in the pads so they are making contact. I might have used a bit to much paste that's why I'm going to repaste it again.

I meant the impression left by the thermal paste on the core when you take the heatsink off.

 

I'll take a picture of it when I open it up here in a bit. It looks relatively even

Sent from my XT1585 using Tapatalk

 

So this is the spread, I am going to reapply I used to much. I hope that will help

First of all the temperature measurement is done via the GPU, and the VRM's have no temperature probe to measure their temperatures.

So, if your GPU temp is jumping immediately upon load, then the GPU heatplate isn't touching the GPU adequately to transfer heat - it's likely those new thermal pads are too thick and keeping the heatplate from getting enough pressure against the GPU can.

Get thinner pads - and it may be that some locations need different thickness pads, so you need to find that out before applying new pads - or removing these new ones - some locations might be ok, you need to determine what thickness is needed where.

Also, @Mr. Fox or @iunlock might have guides for your model as to what thickness pads are used where.

 

Ok, good to know. I used Mr Fox's guide

Sent from my XT1585 using Tapatalk

 

Looks like the gap to the core is still pretty large. Using a bit too much paste should not impact temperatures.

 

Yeah I think I need thinner pads, I used the templates for the sizes but after looking at the old pads the sizes matched but the new pads at firm and the old ones were squishy. I think they squished enough to make good contact and these don't squish at all... I ordered new softer pads, and this is a different version of the VC so the sizes might be different

Sent from my XT1585 using Tapatalk

 

Yeah, you need softer pads for this certainly. When placing the heatsink down CAREFULLY adding a little pressure with your other hand when putting in the screws will also help the pads seat properly.

 

I just got the 780watt power supply, I can see it has two sets of fans - and when the fans are powering down, it makes a screech, either a coil whine or some sort of rotor friction - but it's very annoying, it's like the sound of an eagle - anyone has this?

listen to this when I power it off:

 

So I fried one of my GPUs I'm pretty sure. Liquid metal ftw. I didn't mess up on the GPU die but there was an air bubble and a drop shot out, I thought I got it all but I didn't. Turned it on and black screen. It was the master so I swapped them and the laptop runs fine on one but I want to replace the broke one. That being said anyone know a good place to get another GPU?

Sent from my XT1585 using Tapatalk

 

Sorry to hear that, a moment of silence for the fallen GPU...

We really need to create a thread to keep tabs on all the laptops / motherboards / GPU's bricked by using Liquid Metal.

I see them all the time, mentioned or alluded to, and then nothing.

Most people excited to reap the benefits don't really appreciate the risk. Even experienced people get stung.

Anyway, probably not something you want to hear right now, but I've been wanting to mention it for a while now.

If you approach it nicely you can get your dealer / Aorus to replace that GPU - they know about the risks and how people just want the best, so they will eat a percentage of them - it's early in the release cycle so maybe their LM killed quota isn't used up yet, it's worth asking nicely

 

So lucky it's SLI so I just swapped them for now so the laptop is still running strong. I'm going to contact my dealer and see what they say

Sent from my XT1585 using Tapatalk

 

Talked to my dealer, they are sending me a new one! I never even thought to talk to them I figured they would say no

Sent from my XT1585 using Tapatalk

 

Nope, I don't have that noise. I don't think its normal, but then again, it doesn't sound like anything wrong with it.

 

Yeah, it does that all the time. While I use the thing. The noise while happening is not a problem, but the spinning up and down is very annoying. I've learned to just get used to it, though.

 

So, you think it's he fan itself or coil whine? I can see two solutions. Either we swap the defective row of fans or... make them run all the time? Cooler temps + very tolerable noise, no need for relay switching.

 

In units like P870, P775, P751, i would say that around 80% of clients who change the thermal compound to liquid metal and ACTUALLY carry the laptop around, will get liquid metal spilled into the motherboard. Maybe more then 80%...
I once worked in a place where they offered that upgrade, well most of the units came back fried. I did all sorts of tests but it´s just too hard to be sure it will not spill. Specially after some hours of gaming, you pick the laptop and put it in a backpack, vertically, it´s gone....

 

Pretty sure it's just the fans themselves. Others with the unit have mentioned the spin up/down noise.

 

And this is why I don't even want to consider liquid metal thermal compounds

 

Maybe too much LM and contact between the heat sink and core is not good? Did you try the fix that @Mr. Fox recommended?

 

These 80% are you talking GPUs or CPUs or both?

Sent from my XT1585 using Tapatalk

 

Was actually talking about CPU.
The thing is, it´s hard enough for me (and im used to build/mod), the regular client will do a regular apply, and when he realizes a laptop needs some kind of protection against spills, well, it will be too late.

 

I use Liquid metal on all my laptops. Never experienced problems!! 4 laptops and all works as normal. My daughter throwing her laptop everywhere around. But work as day 1.

 

If it's applied perfectly then it is safe. Any slight extra bit or slight heatsink issue poses a risk.

 

I´m not saying it´s impossible to use it and that everyone will have problems.
I´m just saying that 80% of clients that say "I will use LM, i know what i am doing, it will be safe because i will apply the correct quantity, i never had a problem", yes those same clients, 80% burn the mobos. It´s just my real world statistics.

To do a correct apply you need to be sure you have proper cooler contact.
You need to be sure that you have a fail safe method to avoid spilling like in @Mr. Fox video.

Usually if someone tells me they did a perfect apply, i just remove their battery, do a 30m AIDA extreme FPU and GPU, then put the laptop in a vertical position (disconnected from Power), open it up, and watch the beautiful metal spilling all over. Over the years it´s becoming hard to prove me wrong on this one. There is still a chance that you are in the remaining 20%.

 

You are better off putting something in just in case certainly.

 

I am unable to find any foam pads that are squishy enough or that I can confirm a melting point. Last thing I want is to melt a foam pad to my GPUs lol. But I was thinking would a thermal pad work in place of the foam pads? I have excess thermal pads of .5mm to 3mm.

But I have not applied thermal paste once... I'm sure I could screw up using Kryonaut or something simple, let's not even start talking about what destruction it could cause me to use something so user experience sensitive like using Liquid Metal

 

Start with ordinary thermal paste. Always a first time for all bruh. I'm sure you will get a nice experience. Never say you can't fix it. Even with 4 thumbs you will fix it if you take your time.

 

any idea when we see a new laptop with 8700k? need to see the heatsink!

 

Usually a chip needs to be out before a system can exist for it

 

You need more than just tape to put liquid metal in a laptop. You need some sort of barrier, just like @Mr. Fox 's excellent video. I made a foam barrier for my CPU by cutting out the BGA shape plus a little more for extra clearance, then trimmed the thickness slightly to reduce any resistance of pressure needed for the HS CPU clamp (laptops have much lower pressure than desktops), and it's done its job and been fine when traveling in a backpack. But this is the type of thing where you must do your homework fully. And unlike regular paste like Kryonaut, where applying too much to a bare die doesn't really affect anything, applying too much LM can be dangerous. So make sure you only apply a thin layer, spread it well, and please use a foam dam like the one in @Mr. Fox video, and you should be good to go.

Problems happen when you see people treating LM like regular paste, and one mistake leads to a conductive ball of doom rolling around in a laptop.

 

From @Mr. Fox statement "I tried using one of the very delicate 0.5mm thermal pads and I was pretty sure it was going to work. Well, I was totally wrong, LOL. It was enough resistance to interfere with die contact. I believe, in spite of how soft and fragile it seemed to be, when two flat surfaces came together it resisted compression too much and my temps were crazy high because the heat sink wasn't touching the GPU die. I put Conductonaut on just the die to see how it worked and planned to remove it to apply Conductonaut to the heat sink as well. When I took it apart there was no Conductonaut on the heat sink. It was bone dry."

Or maybe use K5pro to seal corners. This is what I'm planning. https://www.amazon.com/viscous-ther...rd_wg=90eXW&psc=1&refRID=XZP8FRA6P351FBTM3FFR
