I have a i5 2500k processor w/ stock cooler on it but i havent reapplied thermal paste since i built it

[partal]

My CPU gets hotter than it used to get , 70°C , will the temps drop if i reapply thermal paste , processor is i5 2500k with stock cooler

They will most likely go down.

For how much ?

nobody can tell you that, its not an exact science. for the sake of $10 thermal paste its worth a go regardless..

[tlink]

can vary from 2 degrees to like 30 degrees Celsius. depends on so many factors, nobody here can predict it for you.

Temps might go down by 2 - 4C, or more, or less. You probably just have to do it and find out. Arctic Silver MX-4 is one of the best pastes, and the one I'd personally use.

 

Have you overclocked the CPU? With the stock cooler, and those temperatures, I'm guessing not. I recommend getting an inexpensive aftermarket cooler, like a Cooler Master 212 Evo, and then overclocking to 4.5 or 5.6 Ghz. It will be well worth it, and if you're going to reapply thermal paste, might as well, since you're taking the stock cooler off, anyways. The stock cooler isn't very good, and doesn't really allow for a decent overclock to be done.

I cant overclock since my motherboard doesnt support it @Delicieuxz

after markt cooler?

If you're playing $10 for thermal paste, you're paying waaaaay too much

[LogicalDrm]

How much were the temps before under same load? Because 70C is still nice temp with stock cooling. I doubt you will see much effect with new paste.

Arctic Silver 5 was good when it was released but now it lags behind. It's also conductive and has a cure time of about 300 hours which is far from ideal.

 

Better pastes are now available. Noctua NH1, Arctic MX-4, Coolermaster MasterGel Nano and Thermal Grizzy Kryonaut are all better.

Arctic silver 5 is not conductive, I can assure you.

 

"Cure time" isn't a factor. Most thermal pastes work better while they are still moist, but this is a minimal temperature difference. Arctic silver has one of the longest shelf lives out there and while it doesn't perform the best out of the tube, it will continue to work for years. I have a 7 year system that I had to take the cooler off for cleaning with soap and water, the arctic silver was still moist enough that I was able to remove it an re-apply it.
