P75XDM2/P75XXTM cooling!

The thing is you are still restricting them through the smaller fin stack and it messes up the bottom panel to use them.

 

True, but if the fin stack is larger - P770 - then it might help? But I am not willing to try this, my current rear cutout is mostly reversible (Well enough for me not to care), and I don't want to completely destroy my daily driver.

Update: Have the K5 Pro on for a few days, did some basic benchmarks with Timespy/Firestrike and playing Cyberpunk, temps are mostly the same. So it seems like I had my pads placed well enough for contact as my temps have not changed.

At this point I wonder if the P770 heatsinks might be bent accidentally? I will first try the 17 blade fans and see what they do. Then I might as well go with the TM one piece heat sink, if that makes a difference than there might be some warping or something with the heatsink. I was also thinking I might want to try lapping the heatsink, CPU and see if that makes a difference - very carefully of course.

Lastly I looked into the BartX 4.3mm IHS, messaged them, but they are out of stock, are not responding the last ~ month? to messages, so no idea how to get a hold of that.

 

I had to wait aswell till i got an answer from Bartx, dont worry hes going to respond, takes a long time with the corona and stuff. It took almost 2 weeks but i got in touch and ordered a new 4,3mm IHS, i paid for it now i wait till is done and shipped. Hes going to answer just need a little patience

 

The custom Clevo IHS is definitively worth the wait

 

The P770TM would stick out the back of the unit but not be taller.

 

So I got my fans earlier than expected! Woot woot!

Well the fans definitely make a difference! Quick comparison of product numbers:

Fan Comparison:

Stock 13 blade P750:
6-31-P75D3-202
171228
AB08212HX190300
(00DM2)
HYPROBEARING

New 17 blade "upgrade":
6-31-P7753-100
160715
AB08212HX190300
(00DM3)
HYPROBEARING

From ADDA's website for how to breakdown their fan number:
http://www.adda.com.tw/fan.php?act=page

Both 13 and 17 blade fans are:

AB08212HX190300
AB = Blower (Series)
082 = 82mm x 82mm (Frame Size)
12 = 12VDC (Voltage)
H = High (Speed)
X = Hypro (Bearing Type)
19 = 19mm (Thickness)
0 = Blower Blade Shape (Impeller Number)
3 = FG (Function)
00 = Randomize (Fan Type)

So it seems like both the 13 and 17 blade fans are basically exactly the same, except the blade number.

Just looking at the product numbers it seems that the 17 blade fan was from the P775?

Both are:
3Pin
12V
0.50A

Did some more searching because I wanted to find CFM etc, so I just searched "AB08212HX190300" and found:

Results:

So more real testing needs to be done but quick preliminary results show:

TimeSpy:
13 blade fan: @0.912V (~1800mhz) By the end of the benchmark ~85C (auto fans)

17 blade fan: @0.912V (~1800mhz) By the end of the benchmark ~78C (auto fans)

Cyberpunk 2077:
13 blade fan: @0.950V (~1800Mhz) after 10 - 20min ~90C+ (auto fans) Runaway thermals, not safe!
13 blade fan: @0.762V (~1500Mhz), after 20+min ~75C (auto fans) my usual playing setting

17 blade fan: @0.950V (~1800Mhz) after 10 - 20min high 80C+ (auto fans) Runaway thermals, not safe! Still!
17 bade fan: @0.843V (~1700Mhz) after 10 - 20min ~84C (auto fans) still too hot for comfort and I am not sure if it had reached a steady state.
17 bade fan: @0.762V (~1500Mhz), after 20+min ~70C (auto fans) still the safest setting

Full blast fans sounds like a jet plane!! It really sounds like it is pushing a lot more air. So with full fans I can definitely run higher volts and Mhz, but not still not getting anywhere near what yrekabakery is getting.

Not sure if the heatsink is warped? Maybe I should try the P750TM "RTX" one and see how it works in comparison. But that is for later! When I have time.

Also I know other people have probably mentioned this:

https://www.aliexpress.com/item/4000174372901.html?aff_platform=true&aff_short_key=UneMJZVf&isdl=y&src=bing&albch=shopping&acnt=42005546&isdl=y&aff_short_key=UneMJZVf&albcp=373871275&albag=1308419064071836&slnk=&trgt=pla-4585375808811125&plac=&crea=81776241344382&netw=s&device=c&mtctp=e&utm_source=Bing&utm_medium=shopping&utm_campaign=PA_Bing_customlabel1_US_PC&utm_content=customlabel1=7&utm_term=P775 clevo&msclkid=708e310e0bb31a3fe45b511562acc5a0

But since the heatsink from the P770 works . . . wouldn't this also work on our P750?! But just with the fins sticking out the back a little like with mine!? Wouldn't that be cool?!?! There are more thermal pipes, more everything! Even without the liquid cooling hooked up (I do like my lappy to be portable!) it seems like a better thermal solution? It would take longer to reach steady state and I wonder if it would also heat soak too much and not be able to get rid of all the heat?

Okay cool, I haven't heard anything yet, but I will send another message via the website and see if he gets back to me.

True true, but wouldn't the larger to smaller diameter push the air "harder" through the fin stack? I am more familiar with car engines where having a harder intake to a smaller throttle body - depending on build - is a more desirable thing to push more air in.

 

Thats a good improvement by the looks of it! Nice

So are you saying that there is also a version with 19 blades for the p775 series. Do you hava link to it ?

 

My bad! That was a typo, too many numbers running in my mind!


What I am interested in, is if it would be possible to replace the inner fan with another one.

But honestly it seems like Clevo got a pretty good fan/speed/CFM setup already based on the searching I have done.

If more blades = better I know there are other ones that could work?

Like the P870 one ? ? :

https://www.ebay.com/itm/CPU-Coolin...467584?hash=item3433452000:g:HE4AAOSwt55fi1U8

But it is 5v not 12v so less power = not as fast?

Most work needs to be done I guess.

 

A no problem ., think ill buy the 17 blade myself and test them in my p775

A yes i found that for 870 myself, its 5 v so it going to blow up if you use it at 12 .

I found one picture that someone is using a Acer Predator Helios 700 fan inside a P775tm1 and the fan was quieter as the stock clevo ones and behaving the same regarding the temperatures, so its possible to put some other fans inside if they have the same dimension and and very important if they are 12 v.
Want to try this one and see what impact have those many blades vs the clevo one, but its expensive, like 60 euro...if i found a cheap one ill give it a try

See my post here

Oh super interesting that you mentioned the Helios 700 fan, because there is a P775TM on ebay with that mod now!

https://www.ebay.com/itm/Clevo-p775...285301?hash=item28a80052b5:g:6bIAAOSwAQJgEC0u

BTW not bad price point for 2080, especially now when supply is low on basically everything.

 

A yes there i saw that modification aswell , Yes very good price for a 2080

@anassa

If youre interested you can also mod the backcover like i have, cut it with a dremel tool for better thermals , i saw a 5-7 degree difference with the mod on the GPU in w3 and bf5, Cpu temp was not affected, but im using also a notepal u3 with 2 noctua 140 mm fans to blow air directly in the cutouts.

Wait a sec, on AliExpress there is even an P750 version of the custom heatsink??

Even an regular air cooled one?!

https://www.aliexpress.com/item/400...earchweb0_0,searchweb201602_,searchweb201603_

That is cool!

I just realized the previous link also has an aircooled P775 version!

https://www.aliexpress.com/item/400...levo&msclkid=708e310e0bb31a3fe45b511562acc5a0

Dope!

Really expensive, but cool!

 

Ah ya having those fans underneath would definitely help. I don't think the area around the fans are that blocked. But it is an idea.

 

Yes when im upgrading for RTX im going to buy the aircool one and see how it performs


You can try and test with the backcover off and see if you get a difference. Thats how i tested and saw an impact on the gpu with and without the backcover, and after i cut the cover.

 

Good point!

My biggest concern with those custom aliexpress heatsinks, is that I am not convinced it will be able to dissipate the heat better, it will definitely take longer to heatsoak with all that copper, but over a longer gaming session, you will reach the point where the built up heat in those huge heatsinks needs to get cooled, but the fin stack, surface area, size, etc looks exactly the same as stock, so it just means it will take longer to heat up, but still have the same difficulty with dissipating the heat.

Unless you go for the liquid cooled version instead of air cooled, then you got to be careful with the fluids.

 

Good point, im thinking if u have some external fans, like the ones that i have from a coolpad, if they blow on the bigger cooper heatsink it will cool better, need some practical tests

 

Depends if you are at the saturation point for pressure vs flow given the fin density.

 

Hybrid air / water cooling system test for Clevo p750dm2 / dm3 / TMx and Clevo p775dm2 / dm3 / TMx

 

Is this yours!? Amazing temperatures

 

Hello! No, this is a laptop of my client that was modified by his order, I bring Clevo laptops and accessories to Russia from a factory in China, as well as modifications for them.

 

The cooler of the laptop is the one on sale on aliexpress!? This is amazing to be honest

 

Aliexpress is very overpriced, I take directly from the supplier, so it turns out a little cheaper

 

Wow, nice setup and temps, i am impressed. Thinking more and more to get one of these..

 

This radiator is for a liquid cooling system, without it it is able to keep the temperature around 82 degrees under load.

 

You mean the heatsink without the water pump? What Cpu is inside? 9900k and 2080 as gpu`?

 

Yes, the radiator without being connected to a water cooling system will maintain the temperature within 82 degrees under load. The tested laptop has an i7-9700k processor and an RTX 2070 video card, a laptop with an i9-9900kf processor and an RTX2080 video card with a connected water cooling system shows the same temperature results.

 

82C on the GPU isn’t that impressive imo. Turing thermal throttles at 87C so it’s pretty close to the temp limit. Not to mention, the TGP is only 115W on the 2070 and 150W on the 2080, and the dies are huge so thermal density is lower. I get lower than that on air cooling with a much more thermally dense 190W 1080.

 

58 degrees on GPU, do you have less?

 

Ah didn’t see that, video was blurry. If I limit my GPU to 115W and max out fan speed, my temp is in the low 60s.

 

[QUOTE = "yrekabakery, post: 11077936, member: 695118"] If I limit my GPU to 115W and max out fan speed, my temp is in the low 60s. [/ QUOTE]
With hardly believe it, but what will happen to the performance of your GPU and how to deal with the noise from the fans

 

Not bad for the baby model Victor.

 

Max fans sounds like a jet engine, yes. But temps are still reasonable with auto fans and the laptop is much quieter. 115W is very low, basically Max-Q wattage for the 1080, so there will be some performance drop usually. But with undervolt, can just about maintain full clocks at 115W in less GPU power hungry games like Call of Duty: Black Ops Cold War.

 

How do you limit your 1080?

 

I didn’t, my 1080 still has its normal 190W power limit. I just found a game that I know it can maintain full clocks at ~115W with an undervolt.

 

Oh cool. Mine does too. Hopefully I'll be ordering a spi programmer soon to unlock my 1080. We'll see

 

I thought about doing that, but realized even with my thermal mods that the cooling can’t handle much more than 190W, so it would only be for epeen short 3DMark benches that don’t reach heatsoak, plus the fan noise is annoying. TDP modding works great for the P870 though with its vapor chamber.

 

This is what I wanted to show, with a liquid cooling system you get a cold GPU and CPU, an almost silent cooling system and the potential with a headroom for overclocking. Something like this)))

 

You also get weight, leak risks and mobility concerns so it depends on your usage really.

 

Leaks are very unlikely, the design of the radiators excludes this possibility. For mobility, the system is equipped with quick-detachable connectors with a valve inside, and the radiator itself has retained its air cooling system and can be used without connecting a liquid cooling system.

 

Stock P775TMx is limited by the heatsink size and air intake shrouds. This aliexpress block does offer more mass and better surface area for the GPU side from the looks of it, which is a definite plus. Since VRM cooling on the stock heatsink lacks any meaningful surface area.

But had this hybrid actually used microfins for the high heat density areas (die) instead of simple cnc carved tunnels through the copper, it would perform much better both in thermals and noise. Currently it looks to be limited by that and tube sizing for flow rate.

I'm curious as to when disconnecting the fittings, does it require the block to be emptied of water? Because that would mean the channels will be filled with air, which has a terrible thermal transfer coefficient. And how do the fittings react to when internal pressure gets high when it's run without the water pump with water left inside?

 

Of course, after turning off the water cooling system, you need to drain the coolant from the laptop radiator, and this does not affect the ability to remove heat in any way, it is proven. There is also a variant of such a radiator without the possibility of connecting a water cooling system, but only for use with a standard air cooling system, made of a solid plate of copper, which also removes heat quite well, unlike a standard radiator.

 

Would decrease the time to heatsoak maybe a little due to less thermal mass.

 

I guess physics only apply for the rest of us.

 

Yes, what does physics have to do with it?
real use sounded, this radiator on an air system without a connected water system copes well with temperatures

 

Well it depends on the amount of water in the system, exact placement on channels and their path in the non liquid thermal path. I could see it having little impact.

 

I agree with you, but on this radiator, the location of the channels is done correctly, all heat-intensive parts have direct contact with the tubes without a cavity. There are two versions of the filling, in the photo the upper balanced version for air and water cooling systems, the lower one with emphasis on water cooling https://disk.yandex.ru/i/-EJymf9f7xqAiA

 

You might have some differences in core hot spots but with the top design it does look less sensitive.

 

Just to chime in here, having realized that options existed from this thread, my 9700K/1080 in a P750DM2/3G got new 17 blade fans and the heatsink from this AliExpress listing :

https://www.aliexpress.com/item/4000584804041.html?spm=a2g0s.9042311.0.0.5a3d4c4dEaYBLD

I still need to tune a little more (seems like the CPU is running a little warm at the moment, but the GPU no longer begs for mercy with FS2020). The shipping took ~1 month, came decently packed.

Original setup was for 6700K/1060 and the heat from the upgrades was clearly challenging the old cooling system

So far, quite pleased.

 

Yeah that's quite the uptick in parts lol.

 

Just to report back on this. With the updated heatsink and fans, I now get 72 C under full load for my 9700K. That's quite impressive. GPU also seems much happier.
