*** Official Sager NP8378f2(Clevo PB71DF2-G) ***

Yeah you wont get an unlocked BIOS in a machine like this from us but if there are any features you want the default changed on or similar let me know. Undervolting is a handy thing and can help a fair bit.

 

It’s good to see stable temps on this machine I have been considering one from both hid and xotic pc I was kind of leaning towards hid for liquid metal to squeeze out some better temps but I’m not sure that it’s necessary based on everyone else’s temps.

Do you have any game benchmarks you have ran at all Intersted to see just what the temps do with gaming benchmarks

 

CPU hovers low 80s. GPU low 70s. Fan noise is loud. There is no avoiding it with the power usage of this machine. WSAD keys and palm stay semi cool. The T key and just below the center monitor bezel get uncomfortable to touch.

Wondering can you change the fan speed and do you think the laptop is better then asus with same spec

 

The fan speeds can be adjusted, but you can set the fan start setting or the high fan setting. Just change the ramp slope. Also the bios is hard coded to over rule whatever fan profile u set in order to maintain temps. Clevos always have a Max fan shortcut you can turn on at any time using the Fn-1 key.

Whether Asus vs the clevo is any better really depends on what your looking for. Asus' new zephyrus g14 checked all the boxes I wanted in a laptop except for having a 17" screen. I really wanted the bigger real estate.

For me I really wanted a 17" laptop w the new and 4900hs chip paired with a 2070 max q or possibly a 2080 max q. It would be powerful enough for work and games yet should still have the ability to run cool and quiet. If one of those hits the market and regardless of manufacturer, I'll probably sell this one and pick it up.

That being said this machine is fine. I have no real complaints except for the fan noise under load. I've mitigated what I could for now. There's only so much u can do with hot components.

The HS in the right chassis could be very quiet, hopefully we get more variety moving forward.

 

To get the HS designation though manufactures have to agree to AMDs design specification which limits the gpus power envelope. I'm not sure if we'll see a 2070 max q fit into that specification. It nice to dream I guess. Hopefully we'll have more later this summer. I'm thinking August or September.

Real world difference between the HS and H is minimal though, slightly different binning, H models should do fine too.

 

Curious to know if my Out-of-box machine is just running unreasonably hot or if this is expected behavior. This new machine runs way hotter and the fans kick up way more than my old Sager machine. All the below are in entertainment mode

Stats

- 10th Generation Intel® Core™ i7-10875H Processor ( 8 Cores, 16MB Smart Cache, 2.3GHz )

- Intel Wi-Fi 6 AX201 M.2 AX Wireless LAN + Bluetooth Module


Situations :
- Shortly after boot, and sometimes just with the lid closed and doing nothing :
Fans start going nuts, temps at about 80C for about a minute

- Opening the program GitKraken
CPU at 87C! Fans go bonkers. Fans stay on and CPU stays hot for as long as the app is foregrounded

- Transfering lots of files
CPU at 85C and GPU fans going hog wild while Windows Defender uses the integrated GPU to scan all incoming files.

- Unity game development tool + Rider IDE open at the same time
Avg between 75 and 85C on the CPU. GPU about 50. Fans on intermittently. Actually testing the game kicks all the fans into overdrive.




Compare to my older Sager, which handles all this and more while barely breaking above 70C.

Is this *normal* heat and fan usage for this newer model? Or is there something seriously wrong with the thermal compound?

 

It took two days for mine to settle down. I changed the fan profiles to a linear line compared their default profiles. It found the constant high rpm annoying. Now it's quiet but hunts up and down the rpm a little more. Compared to your old one this is a hot running chip. It will hit thermal limits real quick. Undervolting does help. 83C seems to be where the chip will sit under load. I'll see around upper 60 to 70s with Windows background tasks going. I think I idle in the 40s

Interesting. How much load would you say? Currently the machine idles at 55C.

In my case for example, GitKraken alone will stay at about 25% cpu consistently. Rider does that too. Crazy thing is that on the older machine GitKraken doesn't consume anywhere near that much CPU. I don't know what to make of it really.

I don't normally do anything special with my hardware, so could you give me a link to resources on undervolting? It may be possible that the older Sager I have simply doesn't run at full volting in Entertainment mode, and reserves it for Performance mode, since it explicitly has a separate power consumption setting that the newer one doesn't.

 

Performance mode on this thing raises the short term power limit to 107w. Supposedly for up to 43 seconds unless it hit a thermal limit (which is does in 5 to 10 seconds). The beginning of this thread has lots of temps in it under various configurations I was testing. I'd take some time and read through it and see how your machine benchmarks and compares. Download cinebench to test the CPU and see how it does. If your temps and performance numbers match ours your paste is probably fine. You can look into a bit more.

The fans definitely run in this machine much more than my previous.

The only thing I'm not happy about is my ssd #2 hit 103C when xferring about 500gb of data.

Curious Where you buy the laptop from gamedev9001

 

Sager's website

 

When you get a chance can u tell me your bios version?

Thanks for taking the time to answer my questions,

According to msinfo32 : INSYDE Corp. 1.07.03LS1, 9/25/19

Cinebench score on Entertainment was 2379, on Performance 2900. Doing some more tests as I have a chance

 

Sounds like it's just eating an entire thread? Or is it spread out (task manager can view per core usage).

 

It sounds like you have some background processes running. What does task viewer say is using your CPU? Ever hear of a program called o&o shutup10? You can use it to shut off a lot of the windows 10 phone Microsoft background things. One of them being p2p using your machine for Windows updates. That would cause a lot of the background usage going on.

Since your bios is the same you could download Intel's xtu to undervolt. Our won't let us do it in the bios. Undervolting is fairly

Good suggestion, when GitKraken goes crazy it hammers an entire logical core at 100% until it's satisfied. Seems to select one at random, and just go ham all over it. Sometimes it's done with its task quickly, but sometimes it just seems to get completely stuck doing whatever and it hangs onto that one logical core forever.

 

I think you mentioned that as you used the machine the temp dropped. I think this is starting to happen here a bit as well, which is relieving. It's not getting quite as hot in most situations (except when GitKraken comes to the foreground and hammers a single core to death).

Nothing suspicious jumps out when I look at the running tasks. Sorting by power consumption, GitKraken is tops, and also by CPU. It has 5 subprocesses, but only one of them is doing all the work.

Anyhow...

Last night I played Nier Automata and everything was running super hot, and the fans were at full blast. I played Nier Automata again just now, and things were pretty darn cool. I even kept stuff open in the background.

How is it such that using a new machine more would lower the running temperature?

 

That is an awesome question! I really have no idea. Rule of thumb I always used was to give a computer 24 to 48 hours of burn in time to allow the components to settle in. I don't believe kryonaut paste has an official cure time for best performance, but I think most besides liquid metal needs time to bake off the moisture used for spreading it to get the best conduction of heat.bnew machine have lots of background tasks too that start on first installs. I do admit this is the first machine I've ever seen take the rule of thumb so literally . The first two days the fans were always on and loud. Then it settled it to a nicer routine. I was happy that it could surf the web or watch videos without the fans screaming at me. I expected the fans to be loud while gaming or physics number crunching.

If you still want to undervolt I'll walk you through it, but I'm a bit busy w work right now. I have time in the weekend. Htwingnut on the forum had an old post on how to do it using Intel xtu. That's what I used as a reference. I'd search for it if your interested.

I may want to check if undervolting voids the return policy. Somehow I doubt it would, but better safe than sorry. There's something about the way the fans in this unit sound as they approach 80% speed that spikes my anxiety levels, and I might just not even want to deal with having to hear them at all.

 

Yeah, I think this might just not be the machine for me. I can't think straight with the way these fans sound. I can feel my blood pressure rising as they activate.

 

There is a definite whistle at the edge of hearing. I was hoping it would be a bad fan but so far it's been confirmed every unit. It bothered me while surfing the web but not while gaming.
Quiet mode limits the cpu to 15watts.
Power saver is 45w CPU plugged in. 15w on battery and limits the GPU to 80watts on both profiles.

Try making your fan speed profile custom and make it a linear line instead of the one that's in there by default. The fans hunt a bit but run at a much lower rpm. I found it easier to listen to.

Sent from my moto g(7) using Tapatalk

 

It can help somewhat, the problem is that if it's running at all while I'm trying to write code or edit my levels then I can't even think about how to solve the problem at hand, as I'm just too distracted by the fan whistle. I'm with you on it not being such a problem while playing a game, but making them is a little different of a story.

If I put it into quiet mode that does solve the fan noise problem, but then it is only marginally more performant than my 5 year old Sager at normal operating speeds, and the old one doesn't have a high pitched whistle even at maximum fan speeds. At that point, I could just toss 2 new hard drives into the old machine and save myself $2000 for the same effect.

 

Sounds like you're like me and wishing there was a 35 watt power limit setting for the CPU. I keep thinking 15 is a bit too restrictive while paired with the 115w gpu but a 35w setting would give great performance while helping temps and fan noise. I did order a new cooler for underneath but the first attempt turned out to be an Amazon fraud delivery. I have to wait till Sunday for delivery.

I tried using my old 13" laptop cooler but it made temps worse

Yeah pretty much

Are these particular fans something I'd find on other manufacturers machines with similar specifications? Would it be within the forum rules to get a recommendation on a similarly specced notebook from a different manufacturer that may have fans that don't make this particular noise? I don't even think it's so much how loud the fans are as it is the pitch that it makes.

 

I do believe there is an Aurus with similar specs. It has a 90 watt 2070s though. I'm not sure about fan noise. On a side note, what you impression on this laptops speakers?

Sent from my moto g(7) using Tapatalk

 

I'll check that out!

I would not buy the NP8378F2 for the speakers. The onboard audio is markedly less impressive than my older Sager. The speakers are very tin-like in comparison, with less full of a range of sound. The older one isn't quite up to the level of, say, an average MacBook Pro's audio, but it is still very good compared to what I would expect from an average laptop's speakers.

 

I don't have any annoying fan noise on mine, you just hear the air whooshing when it's on full fan speed, no whine, no whir, just air movement.
There's a ton of lappies that have nearly identical fan sizes...perhaps swapping fans themselves ?
Mine idles and does video and web surfing usually under 40C all cores and never hits 50C unless gaming or running benchmarks.
I've also never had the fans spool up at all unless gaming or benchmarking and they are set to auto at all times unless testing a new benchmark and I set them to full speed myself.

 

Yeah sounds like it's looping/waiting on something.

 

Sounds like a memory leak to me....classic poor coding.

 

I upgraded from an NP8173 and the sound blows me away, maxed out is like sitting in front of a TV turned all the way up

Gaming on this thing does make the fans sound like a jet taking off. There's something unnerving about it ramping all the way up as you brace yourself for each iteration, wondering if it can get any higher (yes, yes it can)

 

I really don’t know of any gaming laptop that’s fans don’t get pretty darn loud when gaming. They all ramp up pretty darn loud. You may need a repaste or to raise up the back of the unit.

Definitely this. Temps on this model have always benefited greatly from being raised to increase airflow.

 

It isn't the volume of the fans, it's the particular high pitched, barely audible whine of these specific fans. Remember, I have another Sager from a few years back. Its fans are also loud, but they do not have the same high pitched tone that this model does. The pitch of the motor is much lower, and doesn't really cause the same reaction.

 

The crazy part is that the same software on my older Sager doesn't do anything like this. It certainly doesn't cause the CPU to run at 87 degrees all on its own while it sorts itself out. It's a mystery.

 

Is your other machine an 8 core 16 thread laptop? The program might not have been written to handle so many and is a bit buggy. Hopefully they'll update.

Sent from my moto g(7) using Tapatalk

 

Good call, it is indeed an 8 core. i7-6700K 4.00GHz. I would hope that they'll fix their problems as 10th gen comes into wider use over time, 'cause it's a real problem and it's one of the more usable git clients I've found.

 

6700K is 4 core / 8 thread.

 

Right you are, I was looking at the logical core count. My mistake.

 

AMD riled up the industry we busting the mainstream 4 core Intel limits. It'll take awhile for the software to catch up. We don't have the bios option but I wonder if you were able to shut off some core if your problem would go away.

Ironically it was intel that started the multithread boost to help the I7s over the I5s etc.

 

Interestingly enough this laptop doesn't seem to benefit from being raised. I picked up a new havit 17" cooler with fans and just ran through multiple setups. fans on, fans off, raised on stand with fans on and fans off and temps stayed the same while gamine low 80s for the cpu and low 70s for the gpu. . When I ran benchmarks with or without the cooler I was getting the same numbers.

Clevo did a good job on airflow then for this laptop, I might try a repaste now as a last option and just to see how good the paste job was from sager. This leads me to believe the cpu/gpu heatsink is at it's limit for cooling in this chassis. I'd have liked to see a bit more cooling room so the fans didn't have to run so high, but it's the nature of the beast.

Sweet spot for a comparable performance machine to this would be a 35CPU paired with a 80 to 90W 2080 max q for the same performance with a cooler running machine.

Granted a 2080 will cost you a few hundred extra.

Fan noise was not improved by the cooler either. I was hoping the coolers fans would allow the laptops to run at a slower rpm. There was a slight drop, but not enough to truly matter.

 

Do you think it's possible to get better cooling on this model? I mean, with half the bottom already being devoted to that end.

 

Please post back with your repaste temps very interested to hear your results


Sent from my iPhone using Tapatalk

 

That's really weird since mine saw temps go down around low to mid 70's by simply raising the back of the laptop. Granted, mine was repasted.

 

Hey do you think after doing this and replying back to us, you can tell us everything you've done regarding undervolting and anything you did for cooling with specific numbers
