Malinche Posted September 17, 2008 Share Posted September 17, 2008 Hello. I have replaced and old Chieftech 350w psu with the corsair vx450. The pc has 3 extra fan to cool the hdds..now this 3 fan make an horrible noise (i think they run a lot faster),and the pc has boot problems (black screen,boot failure);however the cpu fan and the vx450 fan seems to work normally. I have replaced the vx 450 with the old chieftech,and now it's all ok,the 3 fans works normally at regular speed with low noise.. Is the VX450 giving too energy or too amperes to my motherboard (because fans run faster)? I'm going to try the corsair psu on another pc. My Pc: e2140@2,8ghz 2gb ram 2 optical units 4hds motherboard gigabyte p35-ds3l ati 1950pro pcie xfi extreme music ups Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted September 17, 2008 Corsair Employees Share Posted September 17, 2008 That is odd, when you changed the PSU did you load setup defaults in the BIOS? Link to comment Share on other sites More sharing options...
Malinche Posted September 18, 2008 Author Share Posted September 18, 2008 The vx450 seems to works good,without problems,on a second pc (athlon 3000+,asus motherboard,radeon 9200,1hd,2 optical units..) Yes,i have loaded the bios safe defaults..now i'm trying the corsair on this core2 pc,and it's working (but something pc doesn't boot) but the 3 extra fans still make an horrible noise so they doesn't work normally (too volts?too amperes?)...so i can't still use them :( Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted September 18, 2008 Corsair Employees Share Posted September 18, 2008 Are these fans plugged into headers on your motherboard, or directly into molex connectors on the PSU? Have you tried different molex connectors? And did you have trouble booting both systems or just the primary system? Link to comment Share on other sites More sharing options...
Malinche Posted September 18, 2008 Author Share Posted September 18, 2008 Hello. The primary system sometimes had boot problems but now it seems ok (i'm using it) the secondary system works ok with the psu. The 3 fans are powered by the psu,i have downvolted them,so they now run slower and make less noise..(but still a bit more noise that with the chieftech) so i think the corsair give more energy to these fan than the old chieftech.

Corsair Employees RAM GUY Posted September 18, 2008 Corsair Employees Share Posted September 18, 2008 I would agree with you, depending on which molex connectors are being used you may get slightly different results. Some molex connectors are "Fan Only" connectors and will usually deliver less power than a standard molex. You should be able to pick up some "Fan Only" molex adapters which will slow down your fans.
