Fortron 400W And Prescott

Hi everyone, first post here after some lurking..

Please don't blame me for my english, it is not my native language.

Recently i got a new 2.8E running @3,5 with 1,44V (HT On).

When under load (ie prime or seti) i have no problems or instability but my PSU blows out some hot air, not so hot like nuclear-meltdown but a little hotter than running my other cpu: 2,4c@3,4 Vcc Default (air was ~ 35�-40�C)

I know that the 400W Fortron Source is quite low on +12 but i know too that fortron is really conservative on his specs...

So my question is if i have to be allerted and slow down my oc to avoid frying my psu or it is normal for this unit to run a little hotter?

My sys is:
P4 2,8E @3,5 Vcc 1,44 (load) HT On
Cooled by Zalman 7000A-Cu
P4C800 Vdimm mod
2*256 Mushkin 3500 BH5 @2,8V (lowest possible)
MSI GeForce Ti4400
2*160GB Hitachi 7k250 Sata
Dvd-Rom
DVD+-R/RW
4*80*80mm Fans (including PSU fan)
1 Cold Catode blue (off 90% of time)

Tks.

My Fortron 530w has pretty warm air coming out of its exhaust, and it's not very loaded. I wouldn't really worry about your PSU - as long as your rails look ok and you're not getting a lot of voltage fluctuation it should be fine. I'd be more concerned about the temperature of your mosfets and the like.

Dont worry about your English. Your post is better then a lot of the ones I see here.

As for the heat issue. If you havent altered anything on the PSU ie; changed, volt modded the fan(s) it should be fine. If the heat really bothers you look into trying to lower your case/mobo temps.

Thank you for the answers.

Got voltages with a digital multimeter at molex under load:

[email protected] Ht on Vcore 1,53: +5= 5,16; +12= 11,88;

[email protected] Ht on Vcore 1,44: +5= 5,11; +12= 11,66;

No fluctuation, with the prescot voltages are under 3% out of range, so i think (according to your suggestions) that this will not be a problem fot my unit.

Any comments on these readings?

Tks!

Edit: Forget to write that mosfets are cooled by some tiny Alu heatsinks and fans are at 12V, the case is a Chieftec Big tower with 1 fan on hdds rail blowing in, 1 on left side blowing in too on nb, 1 in the back slot blowing out, last is psu fan.
