Honestly I'd move that 80mm from the NB to the VRM's. They are what is causing the problem, I've yet to have an issue with the NB.

Water block for Gigabyte motherboard come 2-3 week:(
Very bad original thermal grease and heat pad.
Heat pad for VRM is soft other is horrible in use Southbridge and Northbridge.

Last two Mosfet is covered cca 70percent in VRM.

That is what I will probably do. I've got an 80mm shroud that I made from an old fan a couple years ago, so I may end up doing something similar to your setup with a shrouded fan directly over the VRM's. Surely I am getting decent suction flow over the heatsink from the Corsair 120mm fans up top though.

Earlier this morning...I wrote a review at the EGG...I gave the board 3 eggs and said it was not a 8 core overclockable board.
Good for 4 cores and mild overclock. I really believe, based upon my experience and those of others that have posted here,
that it's not a matter of "IF" you're gonna have a problem? It's a matter of "WHEN". Seems to me the more heat put on the board
by overclocking the cpu, the faster "it will" fail. A high end ASUS for me, sooner than later. That's gonna be my solution. thumb.gif

I am embarrassed again..............frown.gif



Last nite I took the puter all apart and cleaned the PSU filter, cleaned and regooped a video card, cleaned and regooped the CPU heat sink, regooped the Enzotech cooler and bolted it down with real actual nuts and bolts, and then reassembled it.
Now the fan for the Arctic A30 fits into a plastic case which snaps onto the heat sink. The cord for said fan is too long so I have been running it around the outside of the cover to the plug on the mobo. This last time I ran it around between the fan and the case for neatness, plugged the thing in and it ran, then went to bed.
So this morning when I saw those numbers while mostly asleep I freaked. eek.gif After some coffee I looked into it and the CPU fan was not turning. It seems that the cord was distorting the fan frame enough that the fan could not turn. So now the fan is spinning and the cord is snaking all over the place. Here is the normal numbers after running a game for a while. Only the video card numbers are off now. It should read 92C max instead of 52C max.

I suppose you could put heatsinks on the back if you used thermal pads but clearance would be a whole other issue.

Shouldn't have to go through all that just to get satisfactory performance from a board that was supposedly engineered and then marketed for overclocking purposes.


absolutey right. and that's really the bottom line here. IF the board wasn't maketed as an OVERCLOCKER's board it would be fine. Leave everything at stock and no problem.
But that's not how the board is advertised....
MARKETED for OVERCLOCKING? CHECK!
ENGINEERED for OVERCLOCKING? .....opps.sozo.gif

I gave it a 1 Egg, it is okay for use in non 8 core CPU but AM3+ has one more release so for the long run it's a waste of money as most will probably upgrade to a better CPU be it the current 8 core CPUs or the new ones and if they did they would be just as crewed as us, I stressed that in my review so hopefully people see it.

YEP, my 6100 is as good ad as this board is going to get. When the time comes upgade the CPU it'll be a new board to go with it.
I'll post a review at the egg too. I didn't get it from them so I won't be a "verified owner" but I'll do it anyway. We need to bring the average down. New-buyer-Overclockers are being misled. It's wrong.

Yes hajnalka, the VRM heatsink is poorly done. The other heatsinks work well enough for me. I put the Enzotech heat sink on with extra paste and it still runs hotter than I like.

The bios in this UD3 board reset itself today. All is well for now,but who knows for how long?

I've been looking at other boards and this UD3 comes as close as any to being laid out just how I want. So far only the MSI 990FXA-GD80 V2 has a layout that looks like it will work for me. The problem is I'm afraid of MSI boards.

Ozz, this is what I sent to the last email address (newegg-support@gigabyteusa.com) you provided:

"I contacted you to confirm that the motherboard GIgabyte FXA-990 UD3 board does CPU THROTTLING in 100% load stress test (Prime/OCCT) with AMD FX-8320 with frequencies over 4 Ghz after a few minutes for an ambient temperature over 28 degrees Celsius or after longer periods for ambient temperatures below 28 Celsius.
In many regions of the worlds the ambient temperature frequently exceeds 28 degrees..
This is why some technicians from Gigabyte responded that they have tested the UD3 board without encountering throttling.
This situation requires us to buy after market VRM cooling solutions which are NOT cheap.
The second problem: UD3 motherboard has NO option to turn off Application Power Management in Bios. Other users from various forums (overclockers.com) say that you promised to release a new Bios version to address at least this problem... that was over a month ago and still you didn't release the new Bios.

Me and other customers hope that Gigabyte really consider resolving these problems instead of providing empty answers.
It would have been justified to offer us to replace the obvious insufficient VRM cooling heat-sink of the FXA990-UD3 boards with a more adequate one, like the heat-pipe solution on the UD5 and UD7 boards.

Regards, "

Hope it helps.

BTW, I changed my OC strategy a bit:
1. I upgraded my case: now I have a NZXT Phantom 410 (99$ in USA). It's the best case for the money.
2. I added 2 more 120 mm fans (one to double front air intake + one mounted on the inside craddle, directing intake air to the northbridge). I plan to add a second top exhaust fan to further improve on CPU temps.
3. Replaced my 5 year old faithful Sirtec 560 Watt PSU with a new, budget PSU: Intertech (German brand) 750 Watt quad rail (4x20A)
4. Lowered the 140 mm middle Noctua NH-D14 fan until it touched the HS base to blow some air directly towards the VRM HS. I also replaced the Noctua thermal paste with Arctic Silver 5 (it never disappointed me).
5. Removed the 80 mm Glacialtech slim fan that I used previously to cool the VRM area.

The results: Drastic overall system noise decrease, 5 degrees drop on the CPU (due to top 140mm exhaust fan) and no throttling with all case fans at "High". Even with the case fans at "Medium", the throttling appeared only once in 45 minutes.

The test was: CPU:OCCT / Large Data Set @ 4.42 Ghz / 1.4V CPU (bios: +0.000 CPU vcore / +0.025 NB core)
Ambient temp: room 28 degrees C .
Picture coming next.. this post is long enough..
