I don't have any suggestion, but just want to state that it hurt my eyes and heart to see PC that dusty 8O ..... sorry, it's not my business :? , but I couldn't help it ....dust is PCs' enemy along with heat ...
The Noctua, Tuniq Tower, AC Freezer, and theZalman 9700 as well as the Scythe Infininity are about the best performing air coolers you can get. Arctic Cooling 5 and 7 are the absolute best thermal compounds.
Someone hasn't heard about Shin Etsu X23. :wink: I seriously doubt you'd be able to find it in China though. It's hard enough to find a US retailer for it. In all honesty though, Shin Etsu X23 is only 1 or maybe 2C better than AS5 so if you can't find it then don't worry too much as AS5 works just fine.
Thank you for your reply.
I just want thermal compound because when i cleaned my casing i opened the hsf from mobo and then i put it back without any thermal compound. it now runs on idle temp of 46 to 50. Thermal compound is not available in local market. So my friend will go to china in a few days and then he will return after a week.
