If you read around in this forum you will notice that socket a temps are inconsistent. That being said it's hard to know what is accurate or not, there are so many variables. My temps read about 44c under heavy load (prime95 torture test), and because of win98's acpi feature which uses the same functions as cpu idle, my temps drop to like 24c. Mikewarrior2 has a good page about socket a temps, I'll see if I can find the link for you. Btw, 47-49 isn't high if your cpu is under load..
