Depends if you put on a lot of high volts.

My Mobo also does not come with mosfet heatsinks, however it does not need them for simple CPU overclocking because of the power phase change.

If it did not come with them, and you do not use volts higher than your board specifies than I would not worry about it.

Mosfet's cooling is a big must if your going to overclock. Otherwise you will end up with burnt mosfet chips

well as I am a novice and the heatsinks I did see were not over $20 I was interested in getting one but I have a very cool case and so far I have had only 2 problems
the system clock in Bios occasionally needs reset and my HD Blue Ray Adudio went out?
Any Ideas?

Yup.

MOSFETs are prone to thermal runaway. They heat up, their current output becomes unreliable and incosistent...generating more heat...causing more instability.

Your CMOS battery might be dead?

so does anyone know of a compatible heatsink for the mofset on a Biostar TA880GB?

what about the audio? and could something during my build have done the battery?

Is this a brand new build? And I'm sorry, I don't quite understand what the problem is with your Blu-Ray audio is, Can you give us some more information on the problem?

ALSA should be able to talk to your onboard fine...if you have it installed, and have checked your mixer levels.

If you're booting into Windows, and have your Ubuntu clock set to UTC offset instead of local-that can cause Windows to freak out--which causes Linux to freak out...because Windows resets the BIOS clock.

It also depends on the stock TDP of a chip. If you're on a 3+1 power phase and the stock TDP is 95W, you've unlocked and/or overclocked, you will want to put in cooling. But if you are OC-ing a 45W TDP processor, you'll be fine because you're below the limits.
This also counts if you are not using the stock cooler (not using a cooler that blows onto mosfets).

Do the Single heat sink sizes vary as there are mounting holes on my motherboard for one and the single strip heat-sinks come in various sizes. my audio was working and then it went out

Like everyone else said, use the Enzotech MOS-c10. They come with thermal tape, look cool and cool good. I put some on the multiphase inductors on my board because they were transferring heat into the mosfet heatsink (and I burned my finger so bad on one that it has a fingerprint burned into it)

If you were running into problems with your mosfets, your system would shutdown or become very unstable. Or if you are monitoring your core voltage, it will start to ripple more as the power converter becomes unstable.
