I use the Spire Pacific Breeze cooler and thermal paste on my computer. During normal use, my CPU temps range from 32-38*C. Other tips to keep laptops cool and happy:
1. Larger laptops should be kept on a smooth, flat surface to maximize air flow under the fans. Frequent use of the laptop in bed, on a pillow, or on the lap can block the fan vents and cause long-term heat damage.
2. Invest in a temperature monitoring program so you can see what causes heat spikes and what cooling methods are most effective for your laptop. I like MobileMeter
and Notebook Hardware Control
3. Get a cooling fan!
4. If you have the ability to increase fan speed (note: to my knowledge, ALL Sager gaming laptops have this ability), use this ability to cool your notebook down during those times where it stays hot for long periods of time. I always use max fans whenever playing a game of any kind. Yes, it's loud, but think of it this way: A very nice pair of headphones is still cheaper than an out-of-warranty motherboard replacement. Putting your fans into overdrive when needed is the most effective way to prevent reaching meltdown temperatures.
5. As regular maintenance, use compressed air to blow out dust collections from your heatsink, keyboard and fan ducts. When using the cans, remember to hold the can upright and put the laptop on its side. Use something like a straightened paper clip to gently hold each fan still while blowing out the duct. Forcing the fans to spin will create electric energy which may cause hardware issues. If you feel comfortable, it helps to remove the heatsink and keyboard before this procedure to get ALL of the dust out, but it's not totally necessary. Make sure to de-dust your cooling fan while you're at it.
6. While you have the heatsink removed, get rid of the factory-installed thermal pad and goo and install some AS5 or similar thermal compound. Apply a tiny amount where the processor comes in contact with the heatsink. Spread evenly with something that will not leave residue behind (I use either a small folded piece of paper or a palette knife) all over the square, and remove any excess. Remember that you only need a VERY small amount, especially for laptops.
If anyone has other steps to add, please do so. I'm just throwing things out from off the top of my head.Warning signs that your laptop needs some attention:
* Random shutting down while performing a task
* Weird beeps, which may or may not be followed by immediate poweroff (those beeps are coming from your motherboard)
* Artifacting (weird graphic anomalies such as lines, or textures being out of place) during gameplay or any CPU or GPU-intensive program, often preventing you from seeing what you are doing on-screen
* Fans always running faster and louder than they should be
If any of these symptoms are observed, you should swiftly take action using the steps above and the tips suggested by others in this thread. The longer a notebook is allowed to overheat itself, the closer it is to death.
