I recently purchased a laptop and a fan for it. (salesperson said I HAD to have one) It freezes me out when I use it?

I have a supposedly well manufactured HP. It runs extremely hot. It was actually fixed for free after it fried itself due to a heat issue that HP acknowledged.It still runs very hot.

If you ask me, your cooling system sounds like a great idea. How hot does your laptop run without it?

I go to school for computer programming, so I'm quite familiar with the problem. I would estimate about 1/3 of my class carry and use a fan wherever they go, and many of the rest either have one at home or talk of buying one. The purpose of a fan, of course, is to keep your computer colder.

A computer can get QUITE hot, and I've felt laptops hot enough to burn. Keeping your laptop cool will speed it up, and increase it's lifespan. If your fan gets that cold, it's a good one.

I would LOVE a fan like that. If you are just an average computer user - browsing, email, chatting, some light flash games - you will most likely never need a fan like this. The exception is if you use your laptop on a non-solid surface, like your lap, a blanket, your bed, a carpet, etc.These materials stop the internal fans from working properly due to a lack of air-flow, and your computer can become QUITE hot.

When your computer becomes hot enough, it will shut off. It you are using your laptop on a flat smooth surface that isn't blocking the ports and it over heats, it could be for any one of a few reasons. Heavy games can certainly cause your laptop to overheat, running it on high performance setting, rendering graphics - anything that causes your computer to do a whole lot of calculations continuously.

Something like CL certainly won't do it. Playing World of Warcraft might. Internal fans can also stop working, fail to kick into high-speed, or become blocked with dust which causes your laptop to get even hotter.

It's often one of the first things to go on a laptop. Speaking from personal experience, mine overheats and shuts off probably more often then I should allow it. Out of ease, I sometimes use it on my bed, and it overheats almost every time.

This could usually prevented by putting a book or something flat under it, but thats not always the most convenient - all humans get lazy at times. I've also had my laptop overheat playing games, and I've had it overheat BADLY while rendering graphics in direct x (which you will most likely never do). Gh-performance gaming laptops are notoriously bad for overheating.

I have plenty of friends with these laptops that deal with it constantly. So in short, using it on a desk or table doing simple browsing will almost never cause your laptop to overheat, given your internal fans are operating properly and your not on high-performance. Using your laptop on a soft surface, playing games, programming, or anything graphics intensive might and I'd suggest a fan for sure.

It's by no means ''necessary'' but it IS a great idea, especially if your doing any of the things I've mentioned, or even have an older laptop. I would continue to use it when it's convenient, even if you just leave it on your desk, but it's not like you need to use it EVERY time you use your laptop. If you start noticing your computer randomly freezes and/or shuts off often (mine also locks out the hard drive for 30 seconds after but not everyones does) I'd make a point of using the fan all the time, as you likely have a broken fan if your not doing anything intensive.

This will extend the life of your laptop and will certainly increase performance. Saying it was necessary is likely just a sales technique - or your computer might have a history of bad fans. Some brands are certainly worse than others.

Good luck!

I used one on my previous laptop because it got very warm underneath. With the fan, I stopped having that problem. Of course that was also when I used non mac products.

Tired of my laptops dying every two years (not cheap ones either - maybe that was my problem), I bought a mac laptop. It doesn't get nearly as hot and a fan like that serves no purpose anymore especially because the the laptop vents out of the back and not underneath. I have an extra around here somewhere.

This laptop is going on three years old now and no problems with heat or components that haven't been covered by my warranty (disc drive failed and replaced for free; battery wouldn't charge and replaced for free; the cord got corroded because of some water damage - it might have been baby drool but I can neither confirm nor deny this - also replaced for free). As for the fan being necessary, it really depends on how hot it gets underneath. People who travel with their laptops may have a fan at home and not carry it with them.

No the laptop fan is not necessary. It can improve your laptop speed if you are using it in a poorly vented situation, like on your lap or on a blanket. Any major brand laptop should have a sufficient cooling system.

Only the cheaper laptops may over heat with extensive or intensive use. Extensive meaning continued use longer than your average battery time (typically more than 3-4 hours). Intensive meaning you're using your computer's maximum capabilities (if your gaming or doing rendering, video editing, Adobe type stuff) If you paid $1000+ for your laptop, it better not need a fan (if you asked me).

Also, over time, a laptop (like any computer) will get slower and run hotter. You may need the fan boost then. The hotter your laptop runs, the better the chance a component will get damaged.

The hard drive in particular is susceptible, as well as the processor and mother board. I don't know why your computer freezes. It shouldn't.

Maybe it's a hardware issue with Windows 7 (I assume you got 7 with a new laptop, Vista has lots of hardware issues too).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
