P-7805u

I guess I am going to wait till Gateway comes out with a quad core version in the FX line. This is a good deal, but not much of a bump up from the 7811...

 

Or do like some people were talking... get this one with the best buy protection plan for 2 or 3 years. Ooops I dropped it after 2 and half years and get the credit towards the newest FX machine. That becomes a moral decision you'd have to make though.

 

A fan doesn't make air cooler. It makes air feel cooler to objects that are moist (like humans). Not sure what that property of physics is called, but put a fan in closed room with a thermometer, and the temperature will stay the same. It just feels cooler to us because of the moisture in our skin.

To a CPU, it can help remove some of the excess heat, but it cannot cool it down lower than the temp of the air itself. (I think...)

 

Could the 2.4ghz CPU be a P8600? Could Gateway have misses up in lan's favor?

 

I took the heat sink off the cpu and read the numbers straight off the chip. the chip says its a P8400 2.23/3.0/1066 which tells me it should be a 2.23ghz, unless it was somehow mis manufactured at intel and ended it hard coded with the p8600s multiplier, but that doesn't explain the strange cpu identification. It works fine and passes every torture test, so I guess I'm not worried about it, its just strange.

 

WOW you arent lying, this thread is getting alot of newbies in.

 

in an air tight room fans do nothing unless they blow in outside air (which is hot or colder) and are blowing to remove inside air that is hot or colder


all fans do is circulate air, it'd be basically impossible to have a computer running be cooler than room temperature if all you are doing is having a fan blow on it (which also makes not to much sense, you would be blowing heat back towards the vent it's coming out of)

 

You sound smart so I don't mean to doubt you but I just don't see how it can't be doing anything.
When I don't have the fan on and I check the idle temps it gots up to 24c and 26c..
When I put the fan on its the temps I showed you..
Has to be doing something...

 

Lol I don't know, I'm going by the temp readings.
When I place the fan on the laptop its around 4-6c cooler than without the fan around.
Thats all I'm saying..

EDIT: Maybe this is why.. I have the computer raised a bit, so the fan is basically blowing air under it too from the side.

 

The objection isn't that the fan is lowering the temperature, as much as your CPU temps, while running, are lower than room temperature!!

 

You are not taking into concentration, the heat sinks, and fins, heat dissipates off the metal, the fans move the hotter air from the metal faster than with no fan.

 

it's due to the nature of air itself, there's bound to be pockets (example high pressure/low pressure systems), think weather, even in a room it will exist since your's obviously wouldn't be air-locked

it's plausible to garner small variations, but nothing will make much of a giant difference, in a housed room i'd give you a variation of +/- 5 degrees fahrenheit at absolute max (and that's pushing it)

 

Regarding your EDIT--basically the same principle of CPU Coolers for notebooks...lowers the overall temp of the unit by a few degrees, making the CPU run cooler than it normally would without it.

But again, CPU being cooler than ambient room temp doesn't make sense.

 

But your not listening....
The room is 70C on the far wall of the room.. the roomis about 20x20FT.
It could well be 55-60F on this side of the room.
I'm getting the reading from the window air conditioner (turning it on for a sec to see the reading than shutting it off cause its cold outside already lol), so I can't get the temp on this side of the room.

 

Right, but it cannot make something colder than the temperature of the air itself. That is my point. A fan, blowing 70F air over a 100F item, cannot make the item 60F degrees.

 

at this point, who cares, where we not talking about the CPU being at 2.4ghz? , and yes agree, that is imposable to have your cpu cooling that low without help, like cold air blowing on it from a AC unit, or canned air.

 

Ahhh....now the truth comes out! One minute your in short sleeves and shorts in a 70F room, and now it's possibly 55F?? With that much of a difference in temperatures, be careful of possible tornados in your room!

 

I guess we need to find out the physics laws pertaining to heat transfer and if you can make one substance absorb heat from another substance even though that other substance has less heat in it than the absorbing substance. All that while maintaining the same conditions (pressure etc) Now maybe, when you are blowing air, somehow the air density changes and so it is actually denser / cooler and can then absorb more heat. Kind of like an A/C system. Oww, my head hurts now.

 

I say everyone get a space fan, lift your notebook about an inch off the surface, put the fan on the left side blowing directly on it and under it and see what your temps are idling (to the people that have the same notebook as me)

 

I posted awhile back that it was on the far end of the room..
And I am in a tanktop and shorts still to this moment.

EDIT: Also I'm on the east coast. So for your next questions (probably gonna ask why am I in shorts and a tank at this tempature).. I'm used to 4F to 6F degrees in the winter here... anything above 40F I wear T-shirts out everywhere.

 

I vote you. Let us know what you find.

 

This makes my brain hurt, lol

 

I think the 2.4ghz cpu just an odd occurrence and I wont worry about it. Probably a defective cpu or bios or something. Whats more annoying to me right now is the GPU fan seems to come on full speed for a few seconds every now and then, then it drops back down and kind of pulses. Anyone else's do that?

 

If we can just figure out what is happening with SemiGamer's computer, we could reverse Global Warming!

 

Lol.. I'm telling you it has to be the fan..
With my old sony vaio, it does the same thing, drops it down 4-6c with the fan on it the way I have it..

EDIT: I'll remove the fan for 30minutes and post my temps than.

 

by fan do you mean A/C because unless you live outside that's near impossible

 

No, regular space fan.
I'd say its basically doing the same thing as coolers do... Which do lower the temp... I mean its not like coolers are A/C's.. their the same thing.. And I already said this is blowing alot of air under the laptop.. So don't see why its not possible.

 

are you sure it's not A/C, haha

 

I'm not that stupid >.<

 

So far since I took the fan off its raised a bit, its at 22c right now.

EDIT: 24c now.
Also noticed, with the fan the notebooks fan doesn't do the bursts of air every few min.
Without it it just did it 3times since the time I removed the fan.

 

I cant find a direct answer on the thermodynamics issue. I will find out though. There might be something with the air pressure or density being able to absorb more heat than normal and thus super cooling the heat source below the ambient temperature of the source air. I'm a mechanic, and working on a/c systems, you have ambient air cooling a substance indirectly to well below ambient, but that involves a pressure (and a state) change before it goes below ambient. So I don't know, I'll have to ask a physicist if its possible.

 

Without the fan since I posted that I was shutting the fan off.
You guys are the experts so you tell me if it makes a difference..

 

One quick question... Is there an internal microphone in the 7805u? :O I can't find one and I was trying to use skype... gah.

 

Isn't it next to the webcam ?

 

If I drop my 7811, on accident, will I get the $1400 I paid for it as store credit towards the 8705, or the lowest sale price of the 7811? I'd really like to know because I'm | | close to trading them out tomorrow.

 

Well, I tried to enable it by going to "recording devices", but it only shows a "not plugged in" next to the microphone.

 

Hey Guys,

This is my first post. This forum is amazing!

The 1920x1200 and 9800 GTS spec are insane. I was all set on getting a HP HDX18p with Bluray for about $1400 when I saw this deal. I am more of a Hi Def enthusiast than a gamer but this deal is too good to pass up.

Does anyone know if any of the slim Bluray drives fit this laptop? Unfortunately adding a slim Bluray drive to this laptop will push the price to about $1400. Newegg has a Sony drive for $299.

Thanks for your responses ahead of time.

@dsc888, wrong interface....you need a SATA drive.

Basically, I'd just recommend you get a external one for like $80-90 from Frys or when it's on sale, (a liteon external) and just stick it via USB or e-sata cable using either through a casing or piggy back cable.

 

I think the reason why it could be lower than the room temp is the fan hitting the fans in your gateway may make them spin faster, removing the hot air, but as others said, if your room is at 55degrees, that is why . Anyone object to me making an Unofficial Lounge for our laptop..I think it would be a good idea...if anymore n00bs come we could have a FAQ and links and reviews for buyers and such...

 

Are you guys sure about the whole dropping the laptop thing in 2.5years..maybe this thing will ride out to 2.5years and we will be stuck with this and paying for an overpriced warranty.

 

Would it fit? http://tgndirect.com/index.php?opti...op.flypage&product_id=117818&category_id=1985 I am not sure if I would be able to make it fit..pretty sure with the extra material around the screen it is 18"

 

Bravoexo,

Thanks for the info! I will look into that. This forum is really helpful

Bought this laptop last week and its been great so far. Just purchased an extra hard drive to put in raid 0...

Does anyone experience their multiplier and voltage fluctuate in CPUID? My multiplier changes from 6 to 8.5 almost constantly, also my voltage changes from 1.250 to 1.313. Not sure if its normal, or CPUID, or probably speedstep, but there are no bios settings to turn speedstep off...

 

@JYH, it's normal.

 

They'll probably replace it back to tru spec (1440x900) screen ....hence I will not get one. (or at least that's my reason. And also I'll be back to my native soil in 2 months...)

 

weak cpu, but good gpu

 

I prefer that over weak GPU but good CPU

 

If you put your Vista power scheme on High Performance, it bumps the CPU clock to high speed all the time.

 

If you have the accidental coverage we will look up what you paid in the system and you will get that amount back, less what you paid for the coverage.

 

Dude, I work at Best Buy and I've said yes to this about fifty times.
