Although not a true gaming laptop, this version of T500 at least has the dedicated 256MB ATI Radeon Mobility HD3650 graphics, which will be used in load testing the system. The OCCT power supply stress test is used to push both the CPU and GPU up to 100% to really heat up the internal temps. First we'll measure temperatures of the laptop alone.
Surprisingly enough, it was not the GPU temp that became a problem. With both cores of the CPU pegged at 100% it took less than 15 minutes to reach 85°C and cause the laptop to actually shut off. Who knows how hot it might have gotten were it not for the built in overheat protection kicking in. Obviously the OCCT test stresses the hardware much more than the system would see under normal conditions. However if you're gaming on a laptop for several hours it's possible you could run into the same situation, and shutting down mid-frag would certainly be a frustrating experience. Let's see if the Cooler Master SF-19 can help at all.
With the Strike Force SF-19 in place and fans running at full tilt, and the system placed under the same conditions, low and behold we actually saw an improvement of several degrees. The OCCT test ran for the full one hour without shutting down, the GPU temp consistently remained 1°C cooler and the CPU temp stayed 4°C lower, although as I mentioned before, who knows how hot it might have gotten before were it not for the safety shut down.
Let's wrap things up with some final thoughts and conclusion.
