Can these notebook's keep the CPU at desktop type temps? Do they have shorter life spans because of heat? Just curious.

No, they run hot. Or they roar loudly. Or both, like with the P4's
. Pick one.
Technically yes, but you will not notice. More heat always decreases life no matter how small, but tell me, have you seen a cpu go bust because of that before (with the obvious exception of the fan breaking/clogging)? It's like it lasting only 15 years instead of 20, you don't really care. -
I've read the new sager beast 9260 is both cool and quiet, thanks to 4 fans and lots of copper. Its got 4 at lower rpm instead of 1 or 2 at WHIRRRRR.
Honestly, out of all the laptops I've known, I've seen P4 based laptops last significantly longer than M's or turions. They still work, but are painfully slow.
Now, with GPU's, heat matters much much more. And they typically get hotter than CPU's.
I've already fried 5 gfx boards, OC'ing them on stock HSF's. -
I've got a Desktop Pentium 4 in my Alienware (see sig below). The fans are more then capable of keeping the heat down. It doesn't even get that loud. The ATI X800M is the heat monster. It has this tiny weeny heatsink that should be at least doubled in size. Except, if your heatsink fails (I.E. the temp sensor goes haywire like it did on mine) it only takes the processor a few minutes to completely overheat. Otherwise, until my MBP gets here that Alienware laptop with its Desktop P4 3.6 GHz is the fastest computer in the house.

Well have to see in 5 years time, before we didn't have another nondesktop CPU gaming laptop apart from the Clevo 900's untill Arima started making gaming chassis last year, imo they did it right since it uses mobile CPU's. Lets compare my Alienware with a Sager 9260 in a few years, both have the same GPUs but the Clevo (Sager) has a desktop CPU and the Arima (Alienware) has a mobile CPU which operates at 45ºC

My C90S is nice and quiet as long as im not benchmarking it, then its a low humm thats not obtrusive.
Its like night and day comparing a current c2d cpu vs a P4 of the old days.
the P4s were the hottest cpus ever made... who decided to put them in a notebook must have been insane. -
I asked that exact question to a representative at PC Microworks, super laptop computer maker.
They store the Intel Extreme Core Two x6800 inside their system, a desktop processor. Here was their reply if it helps some:
"Although this model is very powerful and produces more heat than other laptops, it does have a much more advanced cooling system with all copper heat-syncs, multiple fans, and heat piping technology, so it will not have problems with overheating. The cooler is an aluminum alloy stand that has additional fans and usb ports and keeps the unit running cooler. Although, it is definitely not required, cooler means faster, so it will boost your performance slightly by lowering the temperature several degrees."
I'm a bit hesitant because the weight of the system is probably 20 pounds...haha...but it's fantastic specs wise. I think I might wait it out for an 8800m to show up and get a Dell XPS with one 8800m inside of it. That should be more than enough. -

Its marketing.
If your CPU reaches the point where it activates thermal-protection (either through thread throttling or speed throttling) then your cpu will be slower.. since that one is less likely to do so (no cpu should in theory, but craptastic heatsinks abound) then it is technically "faster" at clock for clock work.
In order to actually gain performance without raising clockspeed (memory/system bus subsystem assumed constant) you need to cool the CPU to the point just before where the silicon-oxide (or other compounds) "gates" become super-conductors. If you're interested in more, IBM did a study on it and you'll find the info on their website somewhere.. its been quite a few years since I last researched the info.
If you're thinking constructively you'll note some CPU's and GPU's seem to have a "cold bug" which is the point where their signals are getting crossed due to super-conducting elements. Some handle cold fine, others dont like it. -
-
You have to play with LN2 (or Liquid Helium to make Super-fluid LN2 iirc) to really get to the point where you gain performance... but you cant really control temps well enough to get there anyways, let alone controlling the temps across each part of the CPU which requires a different temperature to become near a superconductor...
-
OK STEvil, but if I was willing to put in the leg work you know the time and effort your saying if I get this LN2 and I don't just dump it all over my notebook cause different temps, right? Could I do it? My 1.6Ghz could use a push! Also unless I read wrong now it sounds like you want me to get close to superconductivity where as your other post sounded like you wanted to stay away. I am willing to do the work if you teach me how!
Salesman full of it, dishonest! -
Haha...I don't know whether cooler means faster, but he did provide some satisfaction when he replied and told me that heat issues would not be a problem with that particular notebook. I was worried that the heat from the super desktop processor (not just a regular one but an extreme one!) would shorten the computer life. They say "no!"

Well, I have been doing this high performance noteboook stuff for a long time.
Desktop CPU's for notebooks is not such a big deal... true that the thermal design of the particular notebook must be up to par to handle such power and heat.... but the CPU's that I have monitored recently (within the last 3 years) from desktop CPU's in a mobile environment have shown good temps (well below 50 C during Idle and never gets past 70 C on Load).
I have been using my Socket 939 notebook with a server-class CPU (Dual Core AMD Opteron 175), it idles at 47C degrees and at-load it goes up to 61C degrees.... so definitely a cool notebook.
The last recent notebook(s) that was prone to overheat was the ones using the desktop P4's (Williamette to Prescott)... only the Clevo's had a chance to prevent the overheat... but people did not use [or realize] the Fan Toggle to switch all fans to max speed.
.... that and most people DO NOT know how to take care of their high-end notebooks (monitoring temps, cleaning out fans/vents monthly, using notebook cooler)
Only noobs usually fear the desktop CPU's... which is understandable until you have tried them out, as well work with them more.
In my experience, I [as well as many others] that deal with careless notebook owners that are responsible for screwing up their own systems,
use this term to describe the problem..... U.E.
(if you know it, then you know why I say its U.E. that causes more problems than needed) -
OK, I'm back on planet earth, I don't know what I was thinking!
They are wrong about heat but as posted 15 years and 20 years does not matter. But running faster is BS unless another system has a fundemental problem. -
You need to be right on the edge pretty much. Being super-conductive will mean all 1's and 0's are all 1's (on), there is no resistance. Having normal conductivity means nothing changes, though technically you can avoid electromigration a bit more.. -
Just for the record I do know what sublimation is if that helps? -
Not with LN2 you're not. Liquid Nitrogen if you want to poke that into google..
-
uh, liquid nitrogen is just referred to as LN
N2 is for the gas
pretty much impossible to use LN on notebooks (other than ripping out the internals and LN used for benchmarking purposes.) -
