It may drop the temp a few C or delay throttling, but small heatsinks and tiny fans can only dump so much heat out of the chassis. I did all kinds of things to my XPS, but the largest gain came from undervolting and it still sounded like a leafblower when it was being worked moderately hard. My M1 Macbook on the other hand, is dead quiet on top of absolutely destroying the XPS in CPU performance while having vastly superior battery life. I don't have to run anything out of spec to keep it from cooking itself.
