Voltage regulator heat.

[Antimatter]

Current boards don't appear to have a very good voltage regulator design(thermally). Boards up to KT133A usually had heatsinks attached.
There is a considerable amount of heat generated by the switching transistors(especially when overclocking) that is transmitted into the mobo surface and thereby to nearby capacitors. This could lead to voltage regulator failure in the longer term.

Gluing heatsinks to the switching transistors could be a way around the problem though.

well, yes, there was talk of putting heatsinks on them and the clock gen chip too.

My theory, get a temp probe, if it's too hot, put on a heatsink, easy as, and you should do this for all your electrical components, cause they will die if they get too hot.

you're quite right, especially mobos with 2-phase power circuits. and if anyone out there is thinking of cranking up their voltage REAL high, you need to attach heatsinks.

but again in most cases it's about the long term, and people's attitudes are probably along the same lines as overclocking in general - "i'm going to sell it in a year so it's not a problem to me".

I like my(and my customers') PCs to last a few years so I can turn it into an internet router/multimedia machine/file server/hardware testbed...or whatever.
The longer it lasts, the happier I'll be. A properly set up and looked after system can last for a very long time...even overclocked. :)

i reckon as soonas u get a new mobo slap some heatsinks on the mosfets .. cos you ARE gonna o/c that sucker right?:D

[Volodkovich]

i reckon just have good case ventilation, the mosfets and clock generators arent going to get THAT hot...

you should feel the one on the VRXP then, 150+fsb = where'd I put the eggs?

Remind me of that link from the old forum where a guy fried an egg on his cpu.... :Dlol

The "mosfets" can get well over 70c+ in normal usage.
As i do believe Antimatter pointed out, one of the benefits of 3 phase to to spread the "work" out.
Essentially reducing the overall temp of the mosfets down.
As a general point, if its hot, cool it down.
It cant hurt can it ;)
Well, unless u spread 2 litres of Arctic Silver Epoxy on the mosfets, then slap a heatsink on 'em :D

[Grrr!!]

2 litres?! That would turn a motherboard into a slab of heatsink material wouldn't it? Hey that would reduce the need for a case. It'd look cool too. Thanks for the idea :D.
