Effect of room temperature on the temperature of CPU/GPU?

I ask this because the CPU temperature on my S13A (GeForce 640M LE, intel Core i7, 8GB RAM) is pretty high when I game (I tried on CS:GO), maximum of 93 degrees Celcius when the room temperature is about 19 degrees. I worry about this because it's going to be summer in Australia soon, and room temperature will be about 35 easily.

So my questions are:
1. does the temperature of the CPU get significantly higher in Summer than in winter?

2. Do laptop cooling pads help with bringing down the laptop's temperature? I ordered a Logitech N200 and am curious as to whether my money was wasted.

Cheers!

 

Generally, cooling pads do help slightly. However, i think there are no vents on the underside of the laptop, so the difference might not be that significant.

Temperature will go higher. How steep the increase will be remains to be seen.

In other threads it was recommended to limit the maximum performance of the CPU (e.g. to 99%) while gaming in order to prevent it from using turbo boost.
This should result in a decreased temperature and still offer enough performance for gaming.

 

I really hate the fact that the S13's have the fan on the bottom, at the back of the laptop. If I'm gaming without any pads underneath, it seems like its ventilating straight onto the surface of the desk which seems stupid.

Thanks for your tip. I read that it was 99% minimum, I didn't know about the 99% maximum as well. So that's hrough the Advanced Options under Power Options, right?

 

Yes, there is also a maximum cpu setting. should be right beneath minimum cpu setting.

 

To answer your original question, room temperature plays a crucial role, as the heat drawn from the heatsink by the air flowing over it is a function of the temperature rise, i.e. temperature of the air going out minus temperature of the air going in. The hotter the air going in, the less efficiently it will be able to cool the heatsink, because naturally, the temperature of the air going out can never be higher than the temperature of the heatsink itself. So turning on the air-conditioner on a hot day will help, as will turning down the heating in winter.

But first, make sure the air can flow freely without obstructions. Putting the laptop on a soft cushion is not a good idea as the cushion will envelop the sides of the laptop, blocking the air vents. Laptop coolers offer a non-smothering surface, as well as improved ventilation, so there's a double benefit. Your money is not wasted unless you can't be bothered (or just forget) to use it.

Most of the laptops I have seen vent the air out from one side - put your hand there and you should feel the hot air from as much as six inches away when the fan is going full blast. If you can't feel it, it is time to clean the vents and air passages - they could have become clogged with dust.

 

Thanks for the info. I'm going to the shops tomorrow to get myself a decent laptop cooler. Gotta prep up for gaming during Summer

 

Don't set 99% minimum if you want to reduce temps.

 

What do you recommend I set the minimum to?

 

Set minimum to 5%. Higher than that will tell the CPU to clock up even when it's not being used much.


Setting maximum to 99% will disable Turbo Boost. This will reduce temperatures and performance a bit (normally set to 100%).

Most games rely more on the GPU so disabling Turbo Boost won't affect them much. An exception to this is GTA IV which people say is poorly coded and relies a lot on the CPU possibly causing 100% CPU usage.

 

Thanks for that info. I'll set minimum to 5% from now on!
