Heat Issues

[stickroad]

Hey guys, just opened my computer up and its pretty hot in their, the Memory is warm, graphics card is pretty hot so im slightly concerned. In the BIOS the CPU temp is normally around 45-50 degress, i havent overclocked my machine or anything. So should i be worried?

Thanks

Sorry should have metioned, silly me. Its a AMD Athlon 64 3400+ with the stock cooler, 1GB DDR Memory, ATI X1950XT GPU and a Seagate Hard Disk. Im pretty much boiling it down to the GPU since it never used to get this hot, anyway i can reduce the heat?

Also just reading the instrutions of the Artic Cooler, since i have it already then my Brother came running in and knocked it out of my hand and the bit where the paste is hit the floor, whats the best way to clean it so i can apply some AS5 once i get my new system sorted out? Hopefully tuesday.
