I have an Athlon XP 1800+ on a shuttle ak35gtr. My current cooler is a cheap spire with an aluminium heatsink and a cooper base, cooled by a 22CFM fan. The temp is relatively high, with 28-30 C case temp the CPU temp ca rise up to 50. Moreover, Although the fan is not loud, 31dbA, it spins at 5000rpm, which gives it a high pitch, so i was thinking about an AX7 with a medium speed fan, around 40 CFM. Has anybody tried it? I hope that the temp will fall too, am I right?
