I own a Clevo W860cu(aka Sager NP8690) with a cooling system that generates alot of noise. The cooling system consists of two fans, one for the cpu(intel core i7m) and one for the GPU(ati 5870m).
I cannot provide any noise levels(dB levels) but my personal opinion is that it is much to loud. What I mean is that even when typing this post and with nothing else running on the background it is still quite loud. (while gaming I don't mind the loud fans because I can imagine it is necessary)
By making this thread I am hoping to get some info on how to quiet down my system. Considering the fact that it is notebook we are talking about, most solutions for PCs won't cut it.(e.g. afaik premade fancontrollers don't exist for notebook, the space in the chassis is extremely limited, I can't switch to a case with better cooling support, I can't switch cooling systems(not that I know of) etc.)
"910 results found for notebook cooler" - EBAY HAS IN FRONT OF ME, NOW.
Australian Capital Territory. Bidding starts from 99 cents. I never paid more than $25.
I've bought several kinds: passive (no fan for my netbook) & active (USB powered, with or without extra USB sockets, on/off switch & fan speed control.
On high-powered notebooks like ours, I use self-adhesive air leak foam (hardware shops for external home doors) ... multi-layered, to direct the positive air flow under the notebook, towards the air inlets.
Ensure the hot-air outlets are open - not blocked. Every 6 months I lightly vacuum-clean air holes, STOPPING THE NOTEBOOK FAN FROM SPINNING ----- extremely important, 'cos spinning too fast will destroy it: my direct experience
Use an infra-red thermometer (medical, in-ear, EBAY, ($16+ -- 62 results), very accurate & cheap). Detect where the heat is coming from, top, bottom & sides. Usually I use liquid white-out to record the temps, then put clear nail polish over the numbers. If you want to resell later, write onto write-on tape (eg paper masking tape).
I found the HDD was generating too much heat, so either ventilate the cover (soldering iron many holes through the plastic cover) or remove the cover completely.
I removed it, then hard-jammed & taped the edges of the HDD in.
HP recommend that if you are not using the battery in the notebook, remove it. I did this too. Both the battery & its chamber retain heat.
If the external air temperature is too hot for you, then itt might be too hot to run the computer. Theoretically, very humid air should remove more heat than dry air. So wet things in your room, have living plants or an aerated fish-tank.
