Latest Prema for P150SM?

Hi all,

It's been a 1-2 years since I finally updated the stock Clevo BIOS to Prema, for the main reason that the fans in this thing are absolutely ridiculous. It worked for a few months, but after that it returned to almost the same noise levels as what was happening with stock. At any rate, is there a way to re-flash the BIOS (specifically the fan profile one) so that I can see if it fixes it? The new Prema website changed since I last visited and it doesn't specify where I can download the latest version for my specific model.

After seeing how horrid the fans are in Clevos, I'll never buy another.

Thanks!

 

Clean your system?!

 

I actually did - cleaned all the dust out and applied brand new GELID thermal paste, which did nothing sadly. I can't even load up Google Maps without the fans spinning up to 70-80% speed, not to mention how the speed revs up and down constantly even when idle. Got any other suggestions? I can't do anything on this thing anymore without hearing F-22 Raptor Scramjets in the room.

 

Update Hotkey and set it to Entertainment mode:

Prema BIOS does not help you here mate. Prema Bios is more oriented for people who want to get more performance out of their system rather than having a quiet notebook. In terms of fan profile clevo is the absolute worst. The best course of action here is to mod your cooling to the point where the system has no other choice other than to keep quiet, I have a P157SM so I know all to well how garbage the fan profiles are.

 

Well, that's unfortunate. The Fan profiles that came with the Prema I installed a couple years back helped for a few months, but went back to almost as bad as it was with stock. The only difference now is that the fans never increase to 100% like they used to for no reason, and when gaming. I don't know if you've ever heard what I'm guessing to be 40-60 mm fans or smaller, but hearing those things speed up to 100% in this laptop are absolutely absurd.

As for modding the cooling, honestly how much can this thing possibly be modded, and what sort of mods are we talking about that would shut this thing up? It's not like there is space to plop in 120mm fans to replace the tiny, jet engine sounding fans for the CPU + GPU. Any suggestions?

Cheers!

 

You do not have to tell me, the fans are so insanely loud and to make things even worse are badly pitched as well to irritate your ears even more.Again, I have basicially the same notebook as you, I felt your pain, hence I did a severe cooling overhaul. Also I'm pretty certain your fans louder than stock due to prema EC in the first place. Due to terrible heatsink fit, Prema included an agressive fan profile in the EC to fight the terrible temperatures as well. You can use FN +1 to ramp them at 100% fan speed.

You need heatpipes... lots and lots of heatpipes.. Undervolting, lapping, Sealing airgaps, custom fans (you can steal multibladed fans from another product). To make my system shut up, I had to lapp the heatsink, use ICDiamond (liquid metal performs the same), sealed airgaps, replaced the fans with others which had more blades, CPU got another 2 heatpipes, GPU needed a shim to make good contact, 3 extra heatpipes, added more fins to the heatsinks at the vaporation point and I downloaded a Hotkey version that somehow controlled the fans better. It all ended up with a quiet and relatively cool notebook.

That being said, I had quite warm hardware in my ntoebook (OC 4940MX, highly OC GTX 980M), so you will likely get away with less modding. I'd say try to lapp your heatsinks, add proper thermal paste, undervolt, seal airgapps and see where you got from there.

 

Is there guides anywhere to walk me through how to do all this modding, as well as where to buy all the necessary items? I have modded a lot of PCs (not for quite some time), but I have never modded a laptop, sadly.

 

Not as far as I know (at least not all), I guess I can give you some guidelines etc. via PM to see how far we get.

 

I'm not a full convert yet ...

But why not give liquid metal a try just prepare your system first there are good guides to doing this I will be doing it on my system soon . The preparation is key

Fans will spin less if cooler
GPU's will perform better if cooler
Higher frame rate if cooler
And obviously less stress on hardware if cooler

I have hope because lots of people have seen good results from conductornaut

But remember liquid metal is conductive and can destroy your entire system if you f*&u*%!

 

Liquid metal won't do much compared to high quality pastes in notebooks. Also liquid metal does degrade your copper heatsink over time.

 

What in tarnation are you talking about? Are you next going to tell us gallium based liquid metal TIMs corrode the nickel plated copper IHS too?

 

Of course not. Nickel plated is perfect, however once we talk copper, we have a problem. It doesn't corrode the copper, it defuses into copper over time, which does degrade it's thermal performance. It won't cause any structual damage to copper, only aluminium.

delidded 7700K

 

Proof?

I recall some NBR member posts, der8auer and others say it will cause a discoloration over time and that is it... Nothing about thermal transfer degradation.

I found a post that if you don't like the discoloration, der8auer says using a low solution of HCl to clean it - https://www.hardocp.com/news/2018/04/16/how_to_remove_liquid_metal_residues

But here's another thread talking about discoloration only - https://hardforum.com/threads/how-to-remove-liquid-metal-residues.1958719/#post-1043585411

 

http://forum.notebookreview.com/thr...-compatibility-with-copper-heat-sinks.800890/
This post sums everything up, if you need more, simply google after gallum and inform yourself to confirm the post.

Also I posted a screenshot showing on a P870 with a delidded 7700K where the liquid metal gets stacked against ICD etc. Notebooks cooling bottleneck is an airflow/mass problem rather than conductivity provided you apply high quality thermal paste.

I tested conduconaut against other thermal pastes as well and had similair results. Hence Liquid metal on a notebook is silly.

 

I'll have to go through @Tishers post a little later to see at what temps does this occur. Right now, she mentioned when things get above 300C, there are issues. And if anyone's getting thermals above that temp, they're definitely not using regular computer components any more.

Does that image have anything to do with heat sink degradation over time? If not, then that point is invalid, since I'm questioning only the properties of a heat sink when used with multiple applications of liquid metal over say 12-36 months use on the same heat source / heat sink.

 

No, it's just a test between tims. Basicially showcasing that there is no need to go for liquid metal and damage your heatsink over time + cleaning problem if you can use "normal" tim instead and gain the same.

Also the temperature only dictates how fast the procedure happens, the 300c mentioned by tishers was only when it happens extremely fast. The discoloration, which you can clearly see, is the infusion which I and Tishers mentioned.

Read tishers post again. You'll see temps aren't the reason why it infuses into the copper.

 

I just went thru @Tisher's post again and did some additional reading on Galinstan ( assuming Wiki info is correct ). It seems Cu heat sinks themselves *DO NOT* degrade over time as what was claimed. However, that is different than saying the thermal transfer properties of a Cu heat sink may decrease unless any oxidation buildup is properly cleaned and removed. Note, @Tisher's seems to think it will have a 1 to 2C decrease, but has no proof or studies. However, also as noted, the oxidation buildup tends to lessen over application.

Also as der8auer said, you can remove the oxidation using a low HCl cleaning solution. While I grant you this process is more involved, it is the same principle as removing dust buildup on internal fans. These "barnacles" and crud accumulate over time and they need to be removed. However, just as fan dust is removed, once the oxidation is removed the Cu heat sink's thermal properties will be restored.

 

@Prema hello prema can I also have a bios from you?

 

The oxide layer has higher thermal resistance yes, but it is a very thin layer so as you noted the performance will be slightly lowered. The coatings you see on modern heatsinks does prevent this.

 

Does this include Clevo laptops? If so, which models?

 

Well the tips are darkened on the 150sm but the whole np9877 vapor chamber is coated on the fins. The coating has a small thermal impact too but IIRC it's inbetween.
