Solved Laptop Heating (2 Cores vs. 4 Cores)

Specs: Windows 7, 3.2Ghz/2GB
Hi

I am going to be getting a new laptop soon. The laptop I am planning on getting is the Dell Inspiron 15R (N5110). On weekends I usually use the system for around 5 hours without giving it any rest. I usually browse and then watch a movie and then browse some more and listen to some music.

I was wondering whether a quad-core processor (i7 2630QM 2.0Ghz) in the laptop had more chance of over heating then a dual-core processor (i5 2430M 2.4Ghz) in it when used for about 5 hours without rest.

Waiting for a response.

Both my kids have i7 machines. (HP) In the 12 months they've been in use we have had overheating shutdowns twice. clearing the vents with an airduster dropped the operating temps by about 15degC and only a small amount of dust seemed to be dislodged. So Use a cooling pad but make sure it directs airflow into the laptop vents. One of the pads we bought has only a single central fan but the intake vent for the CPU fan of the laptop is near the edge. There is another larger vented panel in the centre of the laptop but it is only the access cover for the ram & hard drive. Blowing air in there has minimal effect. It has nowhere to go. These cooling pads need only be used when operating with the mains power adapter connected. When operating on battery only most modern machines throttle back the CPU to use less power and extend battery charge, therefore generating less heat. A small can of airduster costs as little as $5 and can deliver 4 or 5 cleaning sessions for a laptop. Use it once a month. $15 per year? Cheap insurance.

In my experience, overheating does not depend on the duration of any particular session, but the intensity of the workload placed on the machine at any given time.

Get yourself a good quality cooling pad to boost air circulation through the laptop vents and periodically clean out the dust buildup with an airduster.

Laptop's overheat because most users don't know how to use them.
core i7 2630QM 45W TDP
core i5 2430M 35W TDP
High TDP = high temperature and high power consumption.

I am planning to get a good cooler master cooling pad. I know that it should be cleaned to avoid dust build up and also it should not be placed on a bed which will block air.

Yes u are right, it should be used on hard flat surface like table top.

So you guys are sure the i7 will not cause overheating if used with care..

Thanks guys... But I'm gonna get the i5 anyway because an i7 would be an overkill for me. I currently have Core 2 Duo and it performs just fine for me and I've never had any problems or I have never felt that it is slow.
