7700 just not cutting it

Post by johnnq » Wed Feb 08, 2006 5:54 pm

athon 64 3200 at stock with a 7700alcu.
antec p180
vf700 5v
3 tricool fans on low

it's just...too..loud. and when the room is warm, it peaks at 50C 5v (like 48 at 12v). should i try and reseat the heatsink by spreaking the paste (i just plopped it on last time), and try to mod it with a nexus fan? or, should i just get a ninja and a nexus and be done with it...? it's clearly making more noise than any other fan in the case which is really dissapointing. i can even hear while the tv is on! :(

is it loud at 5v? or 12v? if its loud at 12v, run it slower?
you might have a mounting problem, because my 3200+ peaks at about 45C with the same cooler at 5v...and my case isnt as good as yours

Greetings,

Maybe a fan swap is required? There is an SPCR article about this -- the Nexus would be a lot quieter. Also, you can likely undervolt the CPU; at least a 10th of a volt or two...it would lower the temp.

Your ambient temp must be the difference -- I built an Athlon 64 3200+ and at stock voltage, using the 7000Al/Cu, it stayed below 42C 95% of the time while Folding passively! That was in an Evercase 4252 with just the Fortron "Green" 300w PS and a 6volted medium speed Yate Loon, running ~900RPM.

I used to have your setup (p180 w/AMD3200+ and 7700 alcu). My idles were high 30's (38-39) 'C (and I live in Singapore so ambient is 26-29'C at night and 33-35'C during the day, in this normally not-airconditioned room). So I'd say its probably your mounting+paste spread.

oh, and I never had the 7700 at 12v, I always had it hooked up to a fanmate, and probably had it turned down to at least halfway.

my idle is around 35ish, but my load is 45ish (goes up to 50 when the room is warm). my point is that i have 3 case fans plus a 7700. the temps aren't anything spectacular and the fan makes a lot of noise (compared to my silent room). i'll try reseating the heatsink i guess.
