Your giving out alot of mixed info.
Is there a model number on the vrms? If there is we could tell which are the cheaper and which are more durable.
They are pretty decent.

ASRock has a lot of boards, it is hard to keep track of them all

After reading this, I'm definitely thinking of replacing my 790FX-GD70. I'm nervous now.

Clocked down to 3.6 @ stock volts for now.

This could be my excuse to finally get a Crosshair IV.

This is why I added a "recommended TDP" column; though the quality may be decent despite things such as non-low RDS, etc. it may be good for certain TDP processors only with cooling.

In other news, a new What VRM cooling will do for you section has been added near the bottom of the article!

At full load it does kick out a fair amount of heat and it's very tight round the back. I have two top and one rear exhaust but still the heat buils up behind the D14. I'm going to cut out the rear fan guard and put a higher CPF rear fan in before trying it turned around.

Of course
The shroud is a good idea.

Nothing useful in the docs. It could well be a northbridge sensor though.. let me set the scene,

I'm using onboard graphics with sideport memory, those are both cooled with a heatsink that's connected via a heatpipe to the VRM heatsink, cooling the rear of the VRMs with a fan lowers the temp3 sensor quite a lot. If it's a northbridge sensor then cooling the VRM part of the sink would in turn lower the temp on the northbridge part of the sink because they are linked with a heatpipe.

If this is correct then cooling the VRMs needs extra attention if using IGP linked to the VRMs with a heatpipe. I'm seriously considering getting a descrete graphics card and disabling the IGP.

Nice update xd. Thanks.

EDIT
What would be a good temp for temp3 if it's a northbridge sensor? Someone here has theirs up to 80C. Whatever it's monitoring those high temps worry me.

Nice post. Would it be possible to form a list of good "value" motherboard

Great read +1. You just schooled me on what VRMs are and how they work.

I'm using a 3 year-old k9a2 platinum v1(4+1 phase) and x6 1090t (125w), is it a timebomb now ? I even disabled Turbo Core in bios so it's 3.2ghz all the time. :\\

Thou I played WoW countless hours on Windows 7 with everything maxed, finished Bad Company 2 in 2 days. Not a single issue. :/

Why did you put Bad quality vrms?
And what does 2 transistors mean?
