*** Official Clevo P870DM2/P870DM3 (Sager NP9873/NP9872) Owner's Lounge! - The Phoenix 2 is here! **

i think it's just cheap noisy fans, haha. perhaps they push enough air, but not the best around.

ADDA fans just have poor bearing.

on a side note. fans dont have to be loud to push a lot of air. loud fan noise is just result of a bad design.

 

i like to play music, when my wife plays Assasin's creed and vise versa

 

thing is that when the fan gets loud - thats the point where it starts to loose efficiency. it's plain physics. thats very relative: loud fans=not very efficient engineering desing

 

Have you tried the Delta 4000 rpm ? Or maybe the Scythes? Those are larger fans and even those are super loud.
Anything over 3500rpm is rather loud by any standard. And even more so if you make it smaller. There is no way to avoid that type of noise, unless you go mag lev.

 

Well, I come from the desktop world, did a lot of watercooling stuff and had tons of fans in my hands from all the known brands. There are indeed fans that push a lot of air and are relatively quiet at the same time.

The problem I have with the ADDA fans on my unit is that they are very loud even at 2000 rpm. I mean a lot louder than Phoenix 1 at 2000 rpm. I have here both units and can compare. And the 12v fans don´t push more air then the 5v fans at the same rotational speed as far as I can tell by holding a paperstripe at the exhaust.

The noise is - how should I say - somehow uneven, the fans don´t seem to be balanced out well, cause vibrations and most importantly, the main source of the noise is generated by the motor itself. Now it seems I have one very bad sample of the 3 fans and CEG will send me a replacement fan. We will see how it turns out once the fan is replaced, BUT:

I fear there is a reason a SLI 1080 from Clevo is cheaper than a Titan GT73VR with 2x1070. Obviously Clevo this time around saved on the fans. I had owned maybe 30 notebooks from different brands (and yes, even if you shoot me now: Apple still has the best haptics and quality in my experience) and from this experience I have a gut feeling that these ADDA fans are crap fans. The fans of Phoenix 1 would push the same amount of air at the same rotational speed while beeing more silent and more importantly having a better noise characteristic.

I am aegerly looking forward to the impression of other forthcoming Phoenix 2 owners, maybe I just have a mondays model but I fear the reality is that clevo simply had chosen the wrong fans this time around.

I already know I will not be happy with ADDA and I hope that someone on this great forum figures out which other brand fan might fit.

 

I am not saying good fans can't be loud. i am saying that when the air in the fan starts to make loud noise - thats where the fan "hits the wall" and with each extra rpm you are loosing gain %.

but the problem with the ADDA fans seems to be in the bearing, not in the sound that comes from moving air.

 

Axial fans are a lot easier to make quiet. But unless you want your laptop vents 120mm tall there's going to be form factor issues there. Compare them instead to GPU fans on reference designs.

I don't know how efficient they are compared to the P870DM fans, but nobody with two brain cells to rub together is going to skimp on one of the most important systems for performance to save $10-20 per machine on a low-volume, high-cost product.

 

very true my friend.

 

I am expecting my DM3 in a couple days.

This issue of really loud fan noise is very concerning. I don't mind loud fans when it is pushed to the max, but if under medium loud it sounds like a vacuum I will be pissed.

This is why I never bought a P35W

 

i'll tell you a secret... 1070 sli is even cheaper than 980m sli was

 

I will have to see from my own sample and compare it to the likes of the p570wm fans.

 

Blower fans are not desktop fans. At a certain point and rpm, noise can only be reduced so much. Some desktop fans have amazing cfm at low rates, but are not blower fans. You must compare type of fans used and by their nature, blower fans are louder! Now there is a question of degree and the static pressure each can achieve at a specific rpm and cfm movement. As such, you make blanket statements without enough knowledge. Go get me the fan specs for each and testing and then we can talk about db ratings.

already trying to find suitable replacement. first gonna try gt72 fan. if only the size fits...

 

Well, in this case clevo could have chosen Sunon Maglev blowers for example.

 

i highly doubt that saving a few bucks on fans would result in the price difference seen to the msi machines

Could you try CB R11,5/15 with stock clockspeed + max fans and monitor maximum temperature in those benchmarks?
I want to see what max temp you get with those 12v fans at fully blast. Thanks if you bother.

i am just talking theory here. if you read carefully, i am saying that the airflow noise can be reduced by a better fan design and yet improved pressure. simply because its not the pressure that makes the noise, but the fan's ability to keep up with the air pressure. once it can't - it becomes louder, the louder it becomes - the less amount of air it moves per consumed watt.

but then again the fans in question have poor bearing, so that has nothing to do with above said.

 

20bucks per barebone, makes 2.000.000 dollars for 100.000 sold pieces.

for example: on BGA 1070 gtx clevo: difference in mono-colored keyboard is around 12 bucks difference from full-colored, why would they offer both?

Gsync BGA machine is also 15buck more expensive than no-g, again why offer both? 60hz vs 120hz - 30$ and so on...

edit: 6700 vs 6700k is also around 30$ dollar difference as far as i remember.

 

Has anyone posted what sort of DB levels the DM3 is making under various loads?

Bit worried

 

That's actually very simple to answer. MSI is too proud of their laptops and charge absolutely asinine prices for them. Very poor value for the dollar, and everything they sell is a BGA turdbook. And, they don't even want you repasting it if my understanding is correct. Touch anything on the inside and *poof* no warranty - from what others have said. I'll never own one as long as all they can offer to sell me is BGA crap, so I have to rely on MSI owners for the accuracy of second-hand information.

 

Nothing like that yet.

 

I would not worry too much yet. Only one person has complained about it. Some folks are more sensitive to fan noise than others, and it sounds like one of his may have something wrong with it. If you have been a laptop beast owner with overclocked CPU and GPU for a long time, probably nothing you're not already used to. If you are super-sensitive to noise, it might be a problem to own any high performance notebook because none of them are super quiet except when they are overheating because of screwed up fan tables (looks at Alienware). Anyhow, we'll get a better idea as more people receive their machines. Might not get any readings on decibels but should get some good readings on perceptions over the next few weeks. Just don't spend your money until the dog and pony show is finished.

This should cover any shenanigans like that.

You are talking theory, I'm taking real world performance. Which fan can replace it that is 12V, can, whether by spec or actual performance, move more CFM beyond the fin array after overcoming the pressure resistance of the array? You show me a better performing fan our a greatly reduced db at the same cfm, then you can complain. Right now you are *****ing based on theory, not on market availability and hard data!

As to the bearings, they might not be the most technological state of the art, then talk about the bearings and what market alternatives there are! Not just saying they are poor quality, especially if one is running louder than the others at the same rpm, which sounds like a manufacturing defect. That is an error specific to a component or device, not general to the line. But once again, that wasn't discussed above either. Just a lot of *****ing without a ****ing solution! So get back to the data, not your theory, and get a solution. Sure, we ***** about bga, but we have hard data to back it up. Even Vizio had low quality TVs, then upped their game (same with LG). You haven't said details on why this one is bad, such as type of bearing used, but instead discuss it is loud and should be quiet. Gtfo!

Edit: sorry for the tone, but the one that is louder than the others you should use warranty to replace. The loudness is likely a defect. The general loudness can be the nature. Look into modding and using the msi 12V fans which currently don't mount and dimensions likely don't fit. My point is, once you show that there was a better market alternative, I'll eat my words. I just need data! If I'm wrong after being PROVEN wrong, I'll gladly admit it. But get that one fan replaced!

People want Mag Lev based fans in notebooks. And then to be able to carry around those notebooks without worrying about malfunction and at the same cost.

Cant have everything people.

Check out Page 65 on wards , specially the noise levels :

Here is how to find the ADDA fan :

Send me a beast, I'll do decibel and frequency testing on it. I have a umik-1 calibration Mic capable of sound level meter and frequency response, which most are more responsive to frequency ranges than the decibel levels (dull roar versus high wine).

Nice try

 

Can never fault a man for trying!!!

OK, maybe this will help. It's not scientific. I just used what I had out in the garage.



The point is loud versus not loud can be a matter of personal perception, just like heavy or not very heavy. If you would ask my wife if my monster laptops have loud fans she would say yes and say she has been putting up with that for at least 10 years. If you asked me, I would say I have no idea what you're talking about.

Likewise, if you asked me if the P870DM-G, P570WM, M18xR1, M18xR2 or Alienware 18 are heavy, I would laugh and ask why such a silly question. But, if you were to ask the thin and light laptop fanboys if those laptops are heavy you would get a totally different answer.

 

LOL. Dunno why im laughing so hard.

 

Nice try Fox. Your video reminds me about Aw 17/18 with Full fan speed done by Hwinfo's fan control vs Dell's very crippled fan control baked in Ec, HaHaaaaa

 

Too late... Already ordered my D3. Due for delivery Thursday this week.

 

wingnut's video is up for p870dm3

 

Reading through this thread, it's almost like a good novel...lol. On to the topic at hand. I am still getting the DM3 but I am likely going to part out one of the 1080's. I came to an agreement with some folks on another forum that it does appear to us that Nvidia is moving away from SLI. Instead of disabling the second 1080 when a game doesn't support SLI (that will be the majority of them), it would make sense to sell it to someone else that will use it. As soon as I can confirm the DM3 will come with a 1080p panel that is G-Sync, I will order it and then go from there.

 

Fair enough, but if you change your mind, you could ask and learn how to use sli on non-supported games as well as learning to overclock and benchmark. I understand we are a special breed of enthusiast, but to hear you will gimp your machine immediately before putting it through its paces and going for gold in benchmarks, even with tight competition, saddens me like I hit to the nuts by a beautiful woman for nothing more than walking over to talk to her...

Edit: and this before I open my mouth so you can't say, well he is an asshole!!!

Not a bad idea to secure the ability to upgrade in the future ...don't have to mess with the hassle of buying an expensive heat sink, let alone dealing with the chassis configuration etc...

Great way to offset the cost.

Any game that does not support sli should pretty much support physx. Use it for that.

 

overkill much?

 

I know SLI very well. In my heyday, I was a stewart of SLI and all of the promise it gave. I have forum posts starting in 05 till about two years ago that I was a Greenie roadie aka an a$$hat fanboy. Go big or go home, but alas single cards seem to be the focus nowadays. I was going to do SLI with the desktop 1080's but I think the fun has been lost. Maybe I am getting old. Give me a good game, a powerful gaming rig and a cup of coffee...I am a happy camper.

 

You know that's a ridiculous question right?

 

What are you talking about, PhysX is the bomb.

 

What are you talking about? I know this.

 

Indeed. Anything in life that is worth doing deserves to be done overkill. Everything else just seems like blasé noob fodder.

I think you misread what was posted.

 

Agreed!
And in this case his second card would not go to waste. Dedicated Physx card for that title.

 

I wonder if anybody could ask @HTWingNut how he feels about the fans, if they're like that front door in Hateful8

​

 

If he is going with 4k, I recommend SLI as it is the only real solution for certain games. However, SLI support is abysmal and with things UE4, SLI is uncertain...

Edit: UE4 games doesnt work at all/well with SLI

 

Here's what I'm thinking. When I get my rig, give me 6 months of play time. Depending on the friendships born on this site, I'll lend the rig to one to possibly do some damage.

I am getting 32GB of G.SKILL Ripjaws 2800, 950 Pro 512GB x2 and a couple of storage SSD's (undecided about those) through Newegg Business. Anything else I should consider?

 

Not really sure what that's about? I was only speaking of what he could do with his second card instead of selling it.

 

That's a nice list you have there. You should be a happy camper.
