Spoiling the new midrange models (1050Ti) party...

i see the confusing now!

i meant from 15pcs i have recently sold!

 

Did you also test prime95 + furmark? because that's the interesting part. XTU cpu-testing is not really intensive at all and as far as I know Clevo lets the CPU temperature run to 90°C anyway before it will throttle (to keep the fan noises down).

 

@Prax0s Where did you get this graphic from (Link)?

Really embarrassing cooling system from Clevo. I guess it will not find many buyers. I dont understand why sager for example would even sell this piece of crap?

 

@Bankfenster, here: http://www.tomshardware.com/reviews/dell-inspiron-15-7000-gaming-laptop,4944-4.html
If I were you, I would just wait for the new heatpipes to launch and the problem of temperatures would be solved

 

Wow these temperatures of the Sager np6852. Not only did Clevo f*ck up the outer design (sharp edges, ports sticking out of the chassis), the mainboard layout, the heatpipes, the fan outlets, but they also f*cked up the temperatures. Everything is FUBAR - but hey, at least they have their exchangable battery. What a joke...

 

@Prax0s Thanks for the link. but I dont think they can make it much better. I think the best we can hope for is that they go for thicker heatpipes for both the CPU and GPU and thats about it. For the CPU a bigger heatpipe wouldnt probably even make much of a difference because the fan is so tiny. I mean just compare the CPU fan of the N850 with this: http://www.notebookcheck.com/fileadmin/_processed_/4/9/csm_IMG_2441_ff3af93eaa.jpg This is the CPU fan from the thinkpad T470, which has a U-CPU. Its kinda funny lol.

@franzerich Yes those temperatures are next level crap. I think I have never in my life seen a worse motherboard layout. I dont know how this mainboard could go through as the final product? Dont they do tests and stuff? Its unbelievable. If a engineer would design for me this kind of crap I would instantly fire him. Thats beyond stupidity.

I think I will go for the Acer VX15 once notebookcheck tested it. Seems to be the most roundup product out there in the 900-1100€ price range with 1050/ti. But it looks disgusting. I dont understand how someone would like this kind of childish design. Even when I was younger I always hated those "gaming" designs. You probably need to be 13 years old max to like it.

 

where are you going to use all that power? i hardly think any game will stress the system as much as XTU does.

 

i wonder if Sager has removed the crappy TIM clevo has used?

and what do you mean by ports sticking out? did you touch the machine itself or just judge by the photos?

 

They used only 1 heat pipe on a 140W GPU(Peak Power Consumtion) , no wonder why it would run so hot

Other manufacturers use dual heat pipe....

 

Spoiler: 1050 Ti cooling comparisons

The CPU and GPU have a dedicated heatpipe, on the other laptops the heatpipes are connected to the CPU and GPU together.

Clevo N850HK1

Acer Aspire VX5


Dell Inspiron 7000


Lenovo Legion Y520


MSI GE72 7RE Apache Pro

Maybe changing the material of the heatpipes help, use copper instead of brass (if Im not wrong). I understand that the more surface area covered, the better it will be.
Also I think it could be the default thermal paste, idk, trying to guess something.

 

And the HP Omen 15: http://www.myfixguide.com/manual/wp-content/uploads/2016/10/HP-Omen-15-ax000-Disassembly-5.jpg
It uses an similiar system like the Lenovo Legion.

Asus Rog gl553: http://www.notebookcheck.com/fileadmin/_processed_/csm_P1030506_66b9a161e6.jpg Not that great. The same as Omen and Legion but with only one fan.

I think out of all cooling systems, the one from the Lenovo Legion looks the most promising.

 

Despite all my criticism about the N850, I can still not rule out, I might have to buy it... isn't it ironic?

Meanwhile I got a HP Omen 15. It was okay, but unfortunately it had a blobb of pixel errors. So I can replace it, or return the laptop and go for another brand... such as a Clevo N850HK1. Back to step 1

Needless to say, the HP Omen didn't convince me fully (so does no laptop). One of the clear advantages from the Clevo is, that I can choose which components I want. The HP Omen can only be bought as a All-in-One package with preset components. If you hate Windows 10, then you are out of luck, because it comes with a NVMe SSD, where Windows 7 can not be installed without major workarounds. Besides the overall HP Omen package is more expensive than a Clevo N850 (200-300€).
*PS: I'll write some lines about the HP Omen 15 in the Hp Omen 15 megathread...

It would be easier to decide, if we had official tests of the N850HK1... we need serious reviews! Also why does Tom's Hardware have temperatures of the Sager NP6852 (N850HK1), but no review?

 

Bro I'm in the same dilemma you are... I was about to buy model Sager NP6852 /Clevo N850HK1, and then saw this topic...

Do you guys know if model Sager NP5855 / Clevo N855HJ (with the NVIDIA® GeForce™ GTX 1050 2GB GDDR5) has the same cooling problems??? And what are the main differences, besides the GPU?

 

here a dutch review of n850hk1
https://tweakers.net/reviews/5229/1...laptop-behuizing-toetsenbord-en-touchpad.html

and this is a review of sager np5855

 

do you know clevo w650kk1 with cpu desktop i5-7500/i7-7700+ gtx1050ti?

 

Hmmm... the dutch review says 70°C for 7700HQ and 75°C for 1050Ti... sounds much better than what Tom's Hardware says with their horrendous 92-100°C

Edit: okay... that was different tests. Dutch review only checked GTA5, while Toms made a Furmark Stress test...

As @Bankfenster I ended up choosing the Acer Aspire VX 15 but for these reviews: https://www.reddit.com/r/SuggestALa...y_the_acer_aspire_vx_15_gaming_laptop_is_the/ and https://www.amazon.com/review/R38X8HK1PGS23D/ref=ask_dp_lswr_rp_hza

This guy has both laptops: https://www.reddit.com/r/LaptopDeals/comments/5y7hd2/the_clash_of_the_top_two_2_gaming_high/

This is my comparison, both seems to be good.

Ah thanks.

What is noteworthy to mention is, that the N850 has also fan profiles like high performance/balanced/energy saving (according to the reddit entry). I recall multiple people asking if this model has it, because they saw no downloads for it on the Clevo site. A very important question solved

 

give me a week and i will solve that dilemma of yours!

and yes, factory TIM is very crappy. also thermalpads need to be replaced because they are too thick!(again Clevo, duh)

 

With nvidia 1050 there shouldn't be throttling while gaming. But we are talking here about throttling while gaming (!!). I mean the 1050ti version throttels while gaming, but for example the Dell Inspiron 15 7000 or the Acer VX15 doesnt even throttel under Prime95+Furmark (!!). Honestly if you ask me, just stay away from this model. The 1050 version may not throttle with full power fans running @ 50dba while gaming, but do you really want to play with such a tornado? Just compare the cooling systems of the Dell Inspiron 15 7000, Acer Vx15, Lenovo Legion,HP Omen or even the previous Clevo model (with the nvidia 960m) with this piece of crap. Its just not worth it. Clevo ****ed up big time.

See the link from prax0s https://www.purepc.pl/notebooki/tes..._smart7_l514c_z_geforce_gtx_1050_ti?page=0,22 The GPU gets to 90°C while gaming (!!). In the Dell Inspiron the 1050ti gets at max 74°C hot with Furmark+Prime95 http://www.notebookcheck.com/Test-Dell-Inspiron-15-7000-7567-Gaming-Laptop.194764.0.html While gaming the Dell GPU gets around 65°C warm, thats a difference of 25°C in comparison with the Clevo N850. At this point its not even sad any more, it starts getting funny lol.

 

I've had my hands on the N850HK1 and I'm super impressed with the 1050Ti. Runs hotter than hell (Hit 94C on max fan profile in Wildlands). I used high quality presets in BF1, RE7, and Wildlands and got enjoyable FPS 40+ without fine tuning anything.

 

Man... that sounds deterring
If it has such high temperatures... is it at least less noisy than similar laptops? I've somewhere read a phrase like "Clevo allows higher temperatures to keep fan noise down". Though not sure if serious...

People who bought from Eluktronics on Amazon seem to be happy about the N850HK1 though... only positive reviews.

 

It's an impressive amount of heat. In fact, I smoke meats with less heat However, Nvidia says it's fine:

http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-1050-ti/specifications

 

Totally subjective from one model/cooling system to another. This one doesn't get very loud, and I imagine those temps can be brought down with a repaste. Some of it is just luck of the draw, too; some chips will run cooler than others.

 

Its the noisiest 1050/1050ti notebook as far as is know. It gets to 50db under load (somewhere in the thread I posted a review where someone measured it). The quietest should be the Acer VX15.

No the cooling system is just ******** and a repaste won't do much. Whether the GPU gets 90°C, 95°C or 97°C hot under load doesnt matter, it simply gets ~20°C too hot, period. Keep it real.

 

Why does the GPU cooling suck so much? Since Maxwell graphics mostly the CPUs overheated, but here it's inverse: CPU cooling is good and GPU cooling is bad.
However it can be seen that the CPU fan has different fan blades... obviously better ones. Why didn't they use the same for the GPU?

 

I wonder if there's an inefficiency of heat transferring through a long single copper plated pipe. My 8153 is a monster but thermals are excellent. The pipes have a pretty short run to the dissipation fins.

Either way, Nvidia says 97C is the max so at 94C we're still good to go.

 

Could you try with liquid metal ? Normal thermal paste like IC diamond 7 has themal conductivity of 4.5 W/m-K
Thermal Grizzly Conductonaut is 73 W/mk which is much better than traditionnal paste
http://forum.notebookreview.com/thr...t-vs-cool-laboratory-liquid-ultra-pro.791489/
You might see 20-30 degree difference

Actually , 85C is pretty high and anything higher than that is dangerous
I have 75W mobile Maxwell GPU and it only hits 70C at full load

 

I can't touch the one sitting here because it's not mine, otherwise I'd love to give it a go. I read that write up you linked and that's pretty amazing stuff!

As someone had previously mentioned, the term "too hot" is subjective when the chip is still under its max temp. However, I'm totally on board with you for getting lower temps.

 

Thanks Equatis for the review, it has been 3 weeks since the N855HJ and I have been waiting for that review of the N850HK1

Many post in reddit says it has good heat management, in other places the opposite, lol...

 

No problem. I'm glad you found the review too. Currently "Unisex Makeup Tutorial" and "Tips for Adoption" videos are showing in my search for "Sager NP6852" instead of my video so I've been worried people wouldn't find it.

 

upgraded CPU cooling! n857hk1 7700hq

 

is it a sager? what model?

mine does not have that "graphiti

mine does not have that "graffiti" on the palmrest fortunately

 

do you have some benchmark in aida64 extreme (stress test)? cpu temps? gpu temps?

 

I have sold the machine today already, all I can say that I have ran XTU stress test, and It was fluctuating from 72-78C after 20minus of test, auto fan profile. with previous cooling it sometimes could go up to 89 in the same stress.

GPU ran Valley benchmark also for 20 minutes, reaching 78C at stock voltage.

then ran it downvolted reaching 70C in the same test

have used Gelid extreme on both CPU and GPU and replaced GPU pads for slightly thinner ones than stock.

if anyone wants to know - don't buy LP156WF6-SPK3 LCD version!! it has terrible color gamut and PWM. even calibrated - the colors look strange.

 

@ tanzmeister

n857hk1 cooling system with 2 heat pipes for cpu is stock or you customized it?

 

It's new stock from Clevo!

 

thanks!!
do you have infos for w650kk1?

 

will have that model to test in around 10 days.

 

What cpu?

 

just barebone. will test with 6700 no K probably
