I've replaced the thermal paste on my CPU three times in the last two weeks because it keeps getting pushed out. While my GPU stays cool below 70°C during heavy gaming, my CPU spikes to over 90°C after just a few days. I'm looking for advice on how to apply thermal paste in a way that minimizes this 'pump out' effect. Has anyone had similar experiences or know any techniques to improve this situation?

It's unusual to see such quick pump-out unless you're using a really thin paste. PTM7950 is a good choice, but there's likely a different issue at play here. Can you share what CPU you're using and your case/cooling setup? That might shed some light on the situation.
When you say 'pump out,' do you mean the thermal paste is being forced out from between the CPU and cooler? That can happen if there's too much paste or if it's too thick. Thermal paste doesn't really melt; it gets squished and can be pushed out under pressure. What CPU are you using? For laptops, hitting 90°C can be pretty normal, especially if you're pushing it hard. Maybe consider getting a cooling stand with a fan to help lower the ambient temperature around it.
I think there's something else going on here. Pump out generally shouldn't happen that fast unless there's a problem with the cooling solution or the paste application. What kind of case and cooler are you using? That could be a contributing factor.
