i've got the athlon xp 1800 & alpha pal 8045 with the enermax adjustable fan. fan set at lower end of scale for minimum noise (~1300 rpm according to cpucool). in an antec 1040 case with one panaflo lo-flow intake, one panaflo exhaust, & the enermax psu w/two fans, my cpu temps were running around 38 idle, 44 load. last night i swapped out the enermax psu for the original antec but replaced the adda fan w/another lo-flow panaflo (despite advertising claims i felt the enermax was kind
of loud). also finally hooked up all the thermal probes for digi-doc 5, including placing one up snug against the athlon die. the result of all this putzing around was a system not noticably more quiet, plus my cpu temps rose by 5C! so here's my questions:
could the thermal probe somehow be hurting my cooling? it's not blocking the hsf contact w/the die.
could the enermax psu be helping keep the cpu cool by having that big exhaust fan right above it?
could it just be that since i was lazy & didn't reapply asII that i just don't have as good a thermal interface between the hsf & die?
could the shim i was using to protect the die (but removed to make room for the thermal probe) have somehow been aiding in cooling?
also, i've been rather dissapointed with the volume of sound generated by my panaflo's. i bought them specifically for the low noise qualities. how quiet can i really expect my rig to be? at current level any ambient noise drowns it out, but if there is no other noise it can be kind of aggravating.
thanks in advance,
joe
