PSU fan revs up noisily

I've a 500 watt psu

winxp
2x 1 gig ddr2 memory
2x geforce 7950gt in sli mode
athlon64 x2 6000+

I've not really had a prob with the PSU's fan noise till today...yep it would rev up when playing intense games. But today I upgraded from an athlon64 x2 4200+ to a 6000+
& at the same time ditched the stock cpu cooler & bolted on a zalman 9700 led heatsink which obviously is putting more sstrain on my PSU.

It's ok under normal load but when I play Graphic intensive games the noise from the psu fan is now almost unbearable. (admittedly also the game settings are now higher as the cpu can handle it)

I'm wondering if this noise is telling me the PSU is being put under strain & it's time to upgrade the wattage?

TIA..Andy.

(two graphics cards probabably doesn't help!)

Oh I forgot theres the usual Hard drive, one dvd rom, one dvd writer, one 120mm case fan, two small (forgot size) case fans. All adds up the wattage!

While I'm at it...these words on here that get underlined & hilighted with popups when you mouse over them..is this something that can be disabled in ie?? (don't ask for much do I?? :)

The new CPU is what's straining the PSU, not the Zalamn. The X2 4200+ is either 65W or 89W depending on revision. The X2 6000+ is either 89W or 125W. Are you sure the noise is from the PSU & not the Zalman?

Why didn't you just overclock the 4200+ rather than spending $135 or so for the CPU & HSF?

Tnx...straining the PSU..Yeah I was saying the new cpu COMBINED with the zalman..(larger fan?) maybe I should have worded it better..So does this mean I need a higher wattage PSU then???? :¬D No it's not the zalman fan as it's on it's lowest rev setting..besides I took the case panel off & llocated where the noisy fan was..ie..the PSU>

couldn't be bothered with going into overclocking know-how..maybe years ago but not anymore...messing about with adjusting this that & the other in bios until getting stable results...hence easier option..anyway...done now.

The old 4200 cpu was 65w. I made sure I got the 65nm 85w 6000+ instead of the windsor core. Else I woulda gone for the 6400+ :¬\

20 watts difference...plus bigger fan...

Still non the wiser.....New psu with higher wattage on the cards?? tnx all the same..Andy.

(ps my airflow is ok too. )


I basically need to know if buying a higher wattage psu will result in quieter operation of the fan due to less straining?

A new PSU isn't gonna do it. If you weren't having the fan noise problem before the CPU/HSF swap, you shouldn't be having it now. You must have inadvertently changed something?

I realize it's your system & your money, but I know I surely wouldn't have wasted $135 for an 800MHz gain in CPU clock speed. Especially when with a handful of BIOS changes, I could have easily gotten it up to at least 2.8GHz.

Well I've not inadvertantly changed anything without knowing about it.....although I have at the same time updated the nforce drivers & also updated the mobo bios so it would recognise the new cpu...apart from that..the only change is in th air flow....from a top-down fan to the cpu to a fan that blows the heat directly into another 120mm outlet fan which is more efficient. I don't think heat is the issue tho as the psu fan fires up on full cylinders as soon as a game starts to run...

My old processor is going into my son's pc..along with the stock heatsink that came with the 6000....anyway it's not a large amount of cash....& whatever you would have gotten the 4200 up to...a new heat sink would have been preferable to the stock cooler in any instance. We all know stock coolers are crap :¬\

You're probably right in the overclocking side but I really couldn't be bothered & would rather spend the extra cash on a faster cpu instead & it really wasnt a discussion I was interested in nor enquired about..merely wanted to know if my 500 watt supply was efficient enough...tnx.

ps....you implied my new processor was straining the psu?
