My laptop computer comes with dual-core Pentium processors and get hot seriously. i have a very limited knowledge about laptop property and i wonder whether one with Core processor dissipates less heat. is it closely related to Pentium or Core processors? which one is better?

Pentium or Core processors?

They would get equally or similarly hot, unless you could fit in a lower-voltage Core 2 processor in there. More and more laptops nowadays have the processor soldered onto the motherboard and aren't replaceable, so this should be kept in mind.
What laptop model is this? Also, download this and tell us what model CPU you currently have. Thanks
EDIT: when taking the laptop apart, it might be dusty in there too. Make sure the laptop is unplugged from AC power and the battery is removed, and use a can of compressed air to clean out any dust in the vents, heatsink, and fans. Having this dust in here can make things hotter.

thanks very much colinstu. i have done as you said and hope it works, while i failed to get the CPU model. i have kept my laptop more than two years and some information marked on it also get worn away. the reason why i want to make this problem clear is that i think it contributes to my next purchase. your words help me a lot. thanks!
How hot a laptop gets is more of a function of the laptop's design than what chip is in it. If you want a laptop that stays cool you need to look at the laptop as a complete system. More powerful CPUs typically will use more power than slower ones, but you can still have a Celeron that melts itself and an i7 that doesn't if the i7 has good cooling and the Celeron has lousy cooling.
i have ever thought by mistake that how much a laptop gets hot mainly depends on what kind of processor it is equiped with .
First things first both "core" and "pentium" are names that have been re-used by intel many times for many very different parts. When you say "dual core pentium" do you mean "pentium dual core" or are you speaking of some other chip that uses the pentium brand and has two cores?
In general newer generations of parts will either do the same ammount of work with less power or do more work with the same ammount of power. They also tend to have lower idle power. In general given the same cooling less power means less heat but of course the cooling setups in laptops vary hugely..

If you have the model # for your processor or for your laptop we might be able to give you some productive advice. I believe that a couple companies put the Intel® Pentium® D processor into a laptop and those would run extremely hot no matter what you did. However if you were using something like the Intel Pentium t4400 then the most likely reason for your heat is that you have trapped dust or a bad fan.
sorry i don't make lt clear. what i said is right pentium dual core.
thanks for your detailed explanation. i have got your idea. thanks!
oh, i see. learn a lot from you guys. so happy
It's all about the Pentiums Baby
Exactly what processors are oyu talking about being soldered in? Super low end ones? Stuff based on what is in netbooks?
All the Intel based laptops have sockets going back to the Pentium 4 days. Not so sure about AMD based laptops, but unless they have recently changed, they should be socketed as well.
The processor in my X220 is soldered in. Processors in macbooks have been soldered in for awhile. Currently intel produces mobile 2nd Gen Core-i3/5/7 processors in both Socket G2 (rPGA988B) and BGA1224 (soldered in) flavors.

Intel branding is very simple
Atom - low end, low power, low frequencies
Celeron - low lend - 1-2 cores, no HT, lower frequencies
Pentium - low end - 2 cores, no HT, higher frequencies
i3 - mid range, 2 cores and HT, higher frequencies
i5 - mid range, 4 cores, no HT, higher frequencies
i7 - high end, 4 cores and HT and high frequencies
Wow, this guy needs help.
Excuse typographical errors, I'm typing on a touch pad.
- if you buy a new laptop any time soon, I'd recommend getting one based on an ivy-bridge processor. It is currently the most efficient with regard to performance per watt.
- laptops often overheat due to excess dust. Clean it out. If a fan is damaged or has failed, then this is another obvious issue.
- yep, the Pentium D ran hot. That was an inefficient generation of processors.
- after that generation, the core and core2 architectures improved our options with regard to efficiency.
- the newer 32nm sandy bridge processors were also quite efficient
- and now the 22nm (referring to size of manufacturing process) ivy bridge processors are better still.
Ivy bridge is particularly good for laptops and for people who do not play games due to the inclusion of the fairly capable hd4000 graphics (some models have hd2500 graphics I think).no separate video card is needed.
My laptop priorities: screen and resolution and size, processor, brand reliability, cost.
I strongly feel that a good site for you to get acquainted with relevant information is: anandtech.com - they often have buying guides, roundups, and detailed explanations about each of your options.
Another recommendation: checkout Wikipedia and find the Intel processor timeline. Quickly observe the names, years, important details, manufacturing sizes of the more recent architectures...
This site is highly regarded for good reason, but it may be better suited for those who are already at least a little bit familiar with the current tech.
You should still ask questions here in this thread as you continue to learn.
Good luck.

Why does the i3 have hyperthreading but the i5 doesn't? If the i3 gets it and HT is a good thing to have, why wouldn't the i5 have it too?

Wow! 7 days into this thread and still no information from OP. about his laptop, You won't get any answers like that.
I'm pretty sure Acer Sheep knows the answer though.

Because than the i5 would become an i7, as the only differences between them is HT enabled on i7 and additional 2 MB of shared cache.
Although some mobile i5s do feature only 2 cores and HT as well.
I wish they made an i7 without HT and called it something else.
An i5? Or turn off HT in BIOS?
Imagine an iMac running windows 7 on an i7. I think i'm gonna be sick.
This doesn't make any sense....? Not sure what you mean?
HT is good but not as good as more real cores.
At least that is true for normal sandy bridge desktop parts.
OTOH Intel's naming/marketing for mobile chips seems to be designed to trick people into thinking an ultrabook is as powerful as a comparably priced desktop or regular laptop.
So when buying laptops don't put any stock in the number after the i, look up the details of the specific model you are being sold.
This is true, but for laptops generally you can go by this:
i3 = dual core no HT 17-35w
i5 = dual core with HT, 3MB L3 17-35w
i7 x6xx M = dual core with HT, 4MB L3 35w
i7 x6xx QM, x7xx QM = quad core with HT, 6MB L3 35w-45w
i7 x8xx QM = quad core with HT, 8MB L3, 45w
i7 x9xx XM series = quad core with HT, 8MB L3, extreme edition, 55w
i3 and i5 are always dual core, i7 can be dual or quad. If there is a QM or XM it is a quad, if it is just M it is dual.

Thanks for your details. really valuable information. i bought my laptop nearly three years ago. it must be equipted with an old generation of processore.
3 years isn't old enough for a Pentium D. Worst case it's a Core 2 or some similar AMD laptop CPU. Both of those are much better than a Pentium D. Pentium Ds are basically a volcano in a box.
Has it always run hot or did it start causing trouble some time after you bought it? If it's always run hot and not much as changed there probably isn't much you can do. It's likely a design issue with the laptop.
If the heat issue started later it's probably just clogged with dust and needs to be taken apart and cleaned. If you can afford to replace the machine I recommend cleaning it yourself. If not hire someone competent. If you're set on replacing it I'd clean it anyway. Learning to take apart a laptop and clean it is good experience, and being comfortable taking apart a laptop will save you a lot in the long run. If one machine gets clogged up cooling the next one probably will too unless something about your environment changes.
Just back everything you need up first, then search the internet until you find a good set of instructions. It's best to read several just in case one leave something out, but I've never needed more than one. You just need to stop, think, study the machine, and have some patience whenever you're not sure. Once you have the machine apart blow it out with canned air. Pay particular attention to the heat sinks and fans. I find taking laptops apart and putting them back together easier than assembling cheap flat packed furniture. It's not hard. Just go slow, be gentle, be careful, and think a bit.

the heat issue started later and it gets hot more quickly and more seriously.
you are so kind. learn a lot from you. and i fell that you are thoughtful. thanks very much.

Today's Pentiums are just really just cut down i3's without HT. (Same as the celerons)
Their thermal TDP is extremely low on the mobile parts. So upgrading won't help. If anything getting a i3 or i5, or i7 would make it worse!
Intel's naming convention is a bit of a failure.
Pentium-M
Core
Core2 Duo
Celeron G Series
Pentium G Series
Core i3/i5/i7
You really need to run CPU-Z and get the model number of the CPU for us to help you out.

all of them are not up to satisfaction?
i have never tried it. something unfamiliar. i have to learn somthing.

I don't think a program could be more easy to use than CPU-Z. All you do is run it, and it tells you all the information you need.

No, i3 sounds dumb compared to Pentium.
i have done it, but i just left the model number of the CPU at my home, now i am in my friend's.
i will offer it later. then how about the ivy bridge?HWinfo? i find i am ignorant.
It's a tiny program just like CPU-Z where the only real thing is opening it and wah-lah all the info is there once its opened.

It does, but it's called i7...
Price premium buddy...Also, 4 physical cores is always better than 2+HT...
