Thermal Pad/ OR no Thermal Pad

Woohoopy · Aug 9, 2013

My heatsink for my Nvidia 540m came with little sticky thermal pads attached to the chip and the Vram. I noticed that the card's heat is stabilizing at an incredible 90c! This is bad as far as I'm concerned, and I'm wondering if thermal paste directly on the vram and chip would be better. Also, could this affect how the heatsink sit? Ex. No longer touches the chip, just the Vram? -Post Note, I put thermal paste on top of the thermal pads when I installed it.

use paste on the gpu and use pads on the memory, do a test run just to check that with the pads on the ram the heatsink contacts the gpu

Hmm... wasn't a perfect fix.
First of all, it took me like 4-5 tries to have the card and heatsink sit where both the vram and gpu chip get cooled. Second, the results are BETTER, but weird non the less.-
Instead of stabilizing at 95º in about 5 minutes of gameplay, the card stabilizes at 79º, but for the next 30 minutes or so, the temperature rises 1º every 3 to 4 minutes. So in 30 minutes time, it once again stabilizes at 90º flat. My guess? Since there is such a low level design in an All-In-One, and since both the separate GPU and CPU heatsinks rely on one fan to cool both of their grill/ radiators, the cool heatsink is initially able to vent off the hot chip, but as time goes on, the inflow of heat is greater than the outflow.

Even more unfortunate, this cheap ass HP Bios has no fan control. (correct me if I'm wrong). I'm wondering if anyone knows of a way to control fan speed independently from the BIOS. (HP Touchsmart 520-1030).
Post-Note, Speedfan doesn't have my motherboard in their database.
