It definitely does for a little while at least. Another thing you could do, which i believed fixed it for longer was to replace the posts that held the heat sink and cook down on the CPU with straight up nuts and bolts. That way you could tighten the cooler down more forcing the cpu to make better contact with the pads on the mobo. I did this to a friends xbox and he got another 2 years of service after this.

Whether or not the towel reflow trick works, I don’t bloody know.
