PWM too hot ?

Abit AV8.

Abit Guru thingy is happy to sound alarm bells when it reaches 80.

Speedfan seems to show flames above 50 (approx)

Atm it`s around 50.

80 is too hot, I wouldn't let it above 60 tbh
 
If 60 is a serious consideration, u think it`d be prudent to look into cooling this another way ?

(54 now btw)

... oh and suggestions for an AV8 >.<

The first thing I do with any motherboard is replace the NB cooling. High temperatures can seriously hinder FSB overclocking and most manufacturers stock solutions are utter shyte.

Before you spend £20 on a new cooler tho, try removing the existing NB cooler, cleaning it up and applying some Arctic Ceramique to it.
 
i have a similar board to you but my probs are different in u guru it says cpu under ext clock , that temp is not of the cpu im suspecting its of the nb its 50 right now under load while the core temp reports 56

pwm 1 45

pwm 2 36

pwm 3 40

pwm 4 34

i have the abit aw9d max
 
PWM (pulse width modulation) are the mosfets for the mobos power circuitry.

It's perfectly normal for those to be the hottest things on the board (esp. with a dual core which draws more current than a single) & they are rated accordingly (the warning level on the digital PWM on my QuadGT is 125C! :eek: ).

You can slap some hs on them or a fan over the area if you want but 50C is fine.
 
Yeah, was kinda the reason I possed the question, I mean from an oc pov, u probably want as good a control over that temp - as u generally control temps.

U would think if a manuf says 80 is a warning temp.... then so be it - but I would hazard to guess that many a board has been sizzled on that theory. 80 maybe the temp under lab stress or summit stoopid.

The board is oc`d, but only taking the 2g to 2.5g - cpu is nice`n`cool under a ninja, and the ram is clocking up from a ddr333 base which only takes it just over 400 with the clock.

It`s hard to see the mobo atm, it`s fitted to a shelf (hard to explain), with a ninja on one side and a 7600 on the otherside of the nb sink. From memory tho, it was a grey`d 70`s looking basic heatsink with a tab either corner to hold it down.

I do have some server type sinks with higher fins, which may do a better job - and the idea of some non-manuf thermal goo sounds like a good idea all-round tbh.
 
80 isn't going to hurt it at stock settings.

80 will probably affect your overclock stability, and potentially the longevity of the northbridge if the heat might be causal because of the overclock.

I bought the thermalright northbridge tower. You can aim it in whatever direction you see fit, and works well with sli setups, or any tight fitting video card area.
