PSA: Liquid Metal Lowers Performance

So. There are indeed cases where a perfect application of liquid metal can LOWER your performance. 

 

An example is my current setup. XPS 13 9370 + Aorus 1080. 

 

What happens on my stock is that as soon as I open a game, the fans don't turn on until 100c. And then they stay on forever. Because the heatsink can't deal with the amount of heat so it stays on.

 

What happens now on LM is that fans don't turn on until 100c, but after running for a while it drops low enough for the fans and the system to be like "Oh, its fine now, let me turn off the fans??????????????". So here I am, taking OFF my LM and getting my stick of Gelid to see wtf is going on.

It sounds like you need to set a custom fan profile to deal with the increased thermal transfer... I wouldn't consider this a lowering of your performance in any way.

 

It's definitely a lowering of comfort, but if you're competent enough to change to liquid metal without destroying your machine, you should be able to adjust fan profiles to account for it.

I wish I could adjust fan profiles, but these things are built into the goddam bios. And it does lower performance. In the past it would run at 3.6-3.7ghz sustained on Witcher 3, but because its allowed to hit TJ Max it causes these massive drops in performance. Goes from 800mhz to 3.9ghz and makes games unplayable as fuck.

Like I said. Dell XPS. Never use.

 

Besides why are you using a 1080 with it? Did you have one for cheap or something?

I have finally moved to a desktop. Also my guides are outdated as hell.

I mean thermally its fine after LM. Its just the fan profiles are completely fucking me right now. I think you have to go below 80c for this to happen after you hit 100c, and it wouldn't happen in the past with stock paste.

SO cheap. I picked up both of these things after selling my Alienware. Got the XPS 13 4k 512gb 16gb for 1800cad and the aorus 1080 box for 600cad. both of them second hand. people have no idea wtf they are selling.

That's part of the problem of it being a XPS though. Cooling and chassis is not the whole laptop. BIOS, fan control, cooling, keyboard, screen, pots, etc is everything combined. I've never been able to find a non-retarded XPS.

600 CAD was pretty good for a 1080, though if buying it just to use in eGPU I would probably sell it for more and buy a 1070 for about the cost price, and notice pretty much no drop in performance. Ever.

Indeed. I wonder if I can break into the bios and adjust fan profile.

Yea, my 1080 is like something like 35% bottlenecked at 1080p.

 

At idle it runs a solid 10c lower. Keep in mind it's passive cooling when idle and on stock it was 51-52c ish. Now its 40. Can't believe its worse when stressed. Also to add more shit to this XPS, the wifi card is a soldered piece of shit killer card. UGH. killer cards give me anxiety. always crashing.

Rest in pepperoni pieces.

 

Meanwhile, I'm here pissing off desktop owners by running 2025MHz in plebg at under 56c

How much does a laptop like that cost though? And at that size it's essentially like carrying a LAN rig around

That's an F in the profile pic

Even a mITX build with peripherals is still much bulkier and heavier to carry. Though I don't really recommend this unit to most. Only if someone absolutely wants all ze power in mobile.

 

My unit specifically cost me $2100.

I figured out the most asinine solution.

 

Took off the LM.

 

Found the LM already eaten into the copper so I lapped the shit out of the heatsink with the highest fucking grit forever.

 

Put on Gelid GC Extreme (I'm not a Kyronaut fan, it has dried out on me on ultrabooks due to low mounting pressure).

 

Put on some Arctic Pads all across the heatpipes and attached it to the chassis. 

 

Solved.

 

Chassis doesn't get too hot even in regular intense workloads without eGPU. 

 

Chassis gets cooled by fan during eGPU loads. This way the CPU never hits 100c because I directed the thermal pads to another sensor to trigger the fans.
