I have a dell inspiron 1520 with the following specs:
Intel Core 2 Duo T7250 2.0GHz
NVidia GeForce 8600GT
I have been monitoring the temperatures for my system and find that for low to moderate loads such as browsing and word processing the temperature are as follows:
Core 0 & 1: Approx 59 - 65C
Graphics Card: Approx 61C
Note: The heat sink is designed such that the heat from the motherboard must pass through the CPU before the cooling fans.
During heavy gaming sessions you can hear the fan work hard and more often than not the computer screen blacks out. I attribute that to overheating.
On a regular basis I can hear the fan working, although when I first bought the system I remember the fan was near silent. Fan and heat sink are both clean, not too much dust. Thermal paste is applied.
I would like to know if any of you have experienced fan efficency decreasing over time and if I should buy a new fan. It's not something that can be directly measured but it is reflected in the temperatures.
Personally I'm not a fan of notebook coolers either. I've always seen them as a bandaid solution to a serious problem.
Thank you. Yeah i'd be surprised if the fan is working at the same efficiency as when it came out of the box. However the component itself hasn't failed per se. It's audible but not enough to make it a nuisance. The air coming out is always warm so I know the fan is doing something. At this rate, in a few years I can turn it into a space heater.
I cleaned it a few weeks ago, at which point I applied a fresh layer of thermal paste to seal the deal.
