Sager NP5790 Review ? Photos, Benchmarks & Impressions Inside!

I am telling you that they do NOT have a custom heatsink. PERIOD.

Its the same stuff from every reseller/vendor... they [Killernotebooks] use stick on those small copper standoffs to the stock heatsink.

So upgrading and such remains EXACTLY the same.

 

The thing about the adding on of heatsinks... is that it must be of a specific height to fit into the chassis, as well as needing to have some thermal tape on the bottom to attach itself onto the surface.

In real world use, you would not get that large of an improving in cooling... 5 C degrees at best.

 

Ok here is the Clevo M570U (aka. Sager 5760, KN Executioner, etc..)

[images clipped]

Look at the heatsink, you see that its stock. They just "modded" it with these:

$8.99 at Newegg.com

So again, Killernotebooks is not re-designing the heatsinks... they are just modding them.... at best.

 

so the 5790 right now, for stock heatsyncs are they using copper or alloy?

 

also will we be able to upgrade to the 'extreme' processor should we choose in the near future?

 

To my knowledge, most of the current gaming notebooks (especially the Clevo models) are using copper heatpipes and heatsinks.

Thats why the latest reviews show that these beasts (D900C and M570RU) runs extremely cool, as compared to previous Clevo models (mainly the previous D900T/K).

 

sorry I move my question here i think i posted it on wrong topic anywayz here is my simple question i dont know if this 1 been ask before
To the Np5790 owners when you are in quiet room does the fan bother you at all. Or if you are in a library you think it is noticeable people who sits next to you can hear it?

 

Joga said that it was pretty quiet. The louder high-pitched fan turned on about every minute, but he didn't notice it until he started listening for the noise. So I bet it's noticeable, but not bothersome.

 

You're right, again, Gophn. They just mod'ed the stock heatsink. But it's quite a spiffy job though when you look at it. I'm not sure how efficient or cooler the mod is compare to the stock. But they do claim that it makes a difference of 22 degrees Fahrenheit cooler, or somewhere around 10-12C. Your estimation of 5C is perhaps more plausible. Maybe it's somewhere in between.

The nice thing though is that they do offer the Core 2 Extreme mobile chips for the Clevo 570RU, which Sager does not offer yet. I just emailed Killernotebooks and was informed that they have the x7800 as well as the x7900 available, for those who have the deep pockets to cough up a spare $499 (x7800) or $650 (x7900) for premium performance. What kind of benchmarks they get with the extreme chips is unknown.

 

Sager, as well as Pro-Star and Eurocom, are more responsible reseller/vendors... because they will stay away from rumors and speculations. They will only give the information that is "official" from Clevo.

Other resellers that use rumors and speculations... especially when advertising can cause future problems for them if they are not correct when posting such information... in a way "misleading" their customers when the facts have not been confirmed.

The mobile X7800/X7900 seems compatible for the Clevo M570RU's chipset and platform... but the official tests have not been confirmed.... but, in this case, I am confident that it will work successfully. (I can say that because I am not a reseller/retailer )

 

Thanks Gophn! We can always count on you to be unbiased. Keep on tellin' it like it is, brother!

 

MXM is only nVidia, right? ATI is left out? Or is it possible that new ATI cards will be "RTF enhanced module!" which is pretty much MXM, with a different name? (The "RTF" was just a generic name.)

And Joga I want Company of Heroes on the Clevo >.< Screenies! I require screenies!

 

gophn were you able to get the temp sensor to work? if i were to get this, iddefinitely like to keep track of the temperature on certain components

Not being an expert and all, it still seems rather implausible to me that sticking a bunch of copper radiating fins on your system could reduce the system's temperature by 22 degrees F. For the sake of a somewhat apples-and-oranges comparison, I found the following review of several desk-top cooling systems:
http://www.anandtech.com/casecooling/showdoc.aspx?i=3001&p=5

and, as indicated in the charts in that review, even an extreme cooler that uses active measures (additional fans), such as Thermaltake's MaxOrb cooler, can barely reduce the operating temperature of a desktop running an Intel X8600 by 22 degrees F. As those charts indicate, the reviewer saw a reduction of 12 degrees C (approx. 21-22 deg F) at idle, and a reduction of 16 degrees C (approx. 28-30 deg F) under load.

The specs on the Thermaltake MaxOrb are here: http://www.thermaltakeusa.com/product/Cooler/Retail/Cl-P0369/speci.html

A cursory review indicates that the MaxOrb is going to provide significantly more cooling than the little copper radiating fins: the system masses 465 grams (equivalent to almost a pound of weight), including the fan, and that the fan itself is capable of forcing 86.5 cubic feet of air per minute through the radiating fins attached to the heatpipes. By comparison, each of the radiating fins in the Thermaltake CL-C0025 that Gophn cross-referenced has a mass of 10 grams each (for a total of 80 grams of copper in a set of 8 units) and is a passive system - i.e., unless the notebook's own fan is pushing air past those fins, very little air is going to flow (other than that caused by thermal convection).

The specs on the Thermaltake CL-C0025 are at: http://www.thermaltakeusa.com/2005/coolers/CL-C002526BGA/CL-C002526BGA.htm

With all due respect to all concerned, and keeping in mind my relative lack of knowledge and experience, it seems to me that it's just a little far-fetched for anyone to claim that sticking a bunch of passive little copper radiating fins around inside the guts of your notebook will achieve the sort of cooling levels that a much larger forced-air system has trouble achieving within the much roomier confines of a desktop case. But then again, that's just my two coppers' worth.

 

A lot of temperature and thermal measurements also rely on the temperature of the room it is tested in. If those claims were tested in a freezer, that's not gonna do us much good, is it? I'd take those claims with a grain of salt if I were you.

 

As gophn & shyster states I doubt 22 degrees is shaved off of the system temp.

We have received some recent info about the Extreme Mobile Processors and the Sager 5790 or 570RU. There are 2 preconditions that Clevo has stated that will need to be met in order to make the Mobile Extreme Processors a option:

a) The maximum temp in the environment is 30 degrees Celsius
b) Intel's "Over Drive" (Intel's name for ocing) will not work due to thermal issues.

Sager will not accept these preconditions so they will not be offering the Extreme processors at this time. Sager is trying to look out for the consumer as they care more for the system's integrity and future health then anything else. The Extreme processors are not a good idea to use at this time in this model.

 

what's unplayable? oblivion with all sliders maxed or Medievil 2? I wanna know about ME2 also please. =)

 

I have Oblivion running on my 7800GTX fine at High/Max settings @ 1920x1200.

Make sure to get the overhaul and tweak mods to optimize performance... while keeping quality the same.

 

with this being said what is the fatest cpu we can upgrade to down the road??? will the motherboard support the new 'peryn' processors?

 

Oblivion stock isn't very well optimized, there are a lot of mods that improve performance or reduce some graphics with little notice by the player, one example would be the Oblivion Grass Mod, it reduces the grass in Oblivion from 16 polygons to 8 or 4 polygons. Big increase in performance, but you don't really notice the reduced quality grass, and who stares at the grass closely anyways?

 

Santa Rosa platform uses Socket P (named for PERYN)

So what do you think?

 

x7900 comes out in September. So Killernotebooks is FOS saying they have it available.

Just another reason why one should stick with Xotic and Powernotebooks. (not to mention their realistic pricing and CS)

 

A good number of these are jumping the gun, even when its not confirmed.

But you cant blame them for being optimistic and confident. .... or can you?

 

Hey gophn when you say tweek mods do you mean for oblivion of system tweeks?

 

both.

i got the grass mod and texture overhaul mods.

I have optimized my system with XP SP2 multi-core hotfix, disable all resource hogs (system restore, anti-virus, etc..), and optimized my Nvidia drivers.

 

About Penryn: today at work I got a chance to play Serious Sam II on a Penryn test model notebook. I might be able to bring you guys some updates next week?

 

Haha, that's coming soon. I'm in the process of downloading the demo - it's 1.8 GB!

 

Yay! Serious Sam II FTW!!!

 

Company of Heroes Demo (in-game performance benchmark):

Settings: 1920x1200, 0xAA, all settings maximum.
Minimum: 12.2 FPS
Average: 22.2 FPS
Maximum: 49.1 FPS

-----------------------------
Settings: 1920x1200, 0xAA, "Automatic" settings (mostly high or max)
Minimum: 12.5 FPS
Average: 25.0 FPS
Maximum: 52.4 FPS

-----------------------------
Settings: 1680x1050, 0xAA, "Automatic" settings
Minimum: 16.8
Average: 34.9
Maximum: 67.2

I honestly couldn't see a difference between any of the three settings, so might as well use the last one

Some screenshots from the third set of settings:

What do you guys mean by express shipping?

is express shipping any other type of shipping option besides the default one? a.k.a. UPS orange, personally I got UPS blue and it just says 3 days so I was wondering if the weekends would count as 2 of those 3 days, if not, please explain, thanks!

 

I followed this guide to the letter but the temperature stays at 0 degrees and doesn't move for my new NP5790 in much the same way Joga described. *shrugs*

As for questions about the optical drive, it's actually quite quiet, though I can feel the vibration on my desk when it starts to spin up at first.

The main fan is so-so loud when it cycles up, but my last laptop was a zd8000 and this is much quieter (man those p4s run hot heh).

Still haven't found any way to manually increase/decrease fan speed :/

 

Glad to know I'm not alone. So it seems that we can't check our GPU temps, and we can't toggle the fans to max. Bummer, but not the end of the world I suppose.

 

I'll have to do some reviewing of why you guys cant check with RivaTuner,

it works fine on the D900C

 

Thanks a lot for the benchmarks Joga. Gophn, or anyone else, do you know if a 2.2GHz processor, possibly OC'd, with an OC'd GPU, will increase performance by much, or is CoH just one of those games?

 

how do i do this w/ ati cards? i have tray tools running but i can't find the option to change prerendered frames

 

When you guys first receive your sager np5790, does it have windows (xp or vista) installed on it (with the drivers?) already? Or do you need to install windows yourself?
If I ordered it with windows xp pro through Xotic PC will it be pre-installed with the drivers? or do I need to install them manually?

 

It will be pre - installed

 

Yeah I couldn't get RivaTuner working either.

 

can someone confirm whether you can measure gpu temps and/or toggle fan speeds?

 

Speedfan gives temps but still no fan monitoring or control.

 

Very nice review, Im expecting my Clevo M570ru next week, I'll post a review as well.

 

I got riva tuner to work on the 5790...the GPU stays at around 45C while gaming for me. The HD heats up lot however. Mine is peaking at 60C right now, that seems way to hot. I think I'm going to invest in a cooling pad to get that temp down.

 

Yeah, I just figured out if you run RivaTuner in Windows XP SP2 Compatability mode, then you can see the GPU temp!

*goess off to do some benchmarking*

 

Updated the review: cleaned it up a bit, added Company of Heroes benchmark, and the biggy: added temperature benchmarks with and without the Zalman cooler.

Conclusion: The Zalman rocks hard.

 

nice, thanks!

may I ask if you used gophns guide to monitoring your GPU temps or did you just use the Nvidia Control centers temperature gauges or...an etc. method?

EDIT:whoops sorry...I wonder how you get rivatuner to monitor your GPU temp in vista...

 

Just right click the RivaTuner shortcut, select properties, and run it in Compatability mode for Windows XP SP2 (and probably run as administrator, although I wouldn't know since I already disabled UAC). I didn't really follow Gophn's guide, I just opened the monitoring graphs and read the core temp from it.

 

ah alright thanks, just a question, how do you access the UAC?

 

Control Panel -> User Accounts -> User Accounts (again) -> Turn User Account Control on or off

 

alright thanks...just another question...do you think the laptop will have problems with overheating without a notebook cooler? thanks!
