I have one 120mm CM sickle flow blowing on my VRM/NB but i did not see any temps drops.

I played some high demanding games for over 1 hour with and without the fan but i did not see any difference in temps to be honest, but it keeps within 27/43C so that should be ok thumb.gif

I heard they are rated for 80c but what i notice it to keep them under 70c gives most stability because when mine hit 73 i get all blue screens and was not stable at all.

Also, I just saw this picture in the thread discussing the possible FX-9000 CPU, which is basically a PD tweaked and ramped up to 5GHz stock clock... Anyways.. an article linked with this picture is what caught my attention and kind of makes me want to call BS...



Anyone with a UD7... did you ever see this anywhere on the packaging or on Gigabyte's own website? Cause I've never heard of any board talking about support of next gen AM3+ 5GHz CPUs... Rumor is that this is supposed to be the next UD7 revision for the updated power thirsty FX CPUs, but as the picture shows, they're advertising using Ultra Durable 4 hardware, not the Ultra Durable 5 that all UD5s and UD7s came with... Why be cheap and put lesser NB/SB/VRM hardware on these boards when the reported TDP of the processors they're designing this board for is rated at 220W... almost 100W TDP more than the current top end FX81-xx/83xxs?

If you place the fan on top off and pulling air away from the VRMs instead of pushing it onto them, you'll probably notice an actually temp change, maybe not more than a few degrees, but it's still a difference, lol.

using my IR gun i actually notice better temps on the VRM with my 80mm fan blowing down than pulling air away.

Here is my setup

Space,
My current machine is using the same UD7 (I own a rev 1.0 and Rev 1.1) the 1.1 is in my machine now and the current 8+2 VRM is capable of handling 220 TDP with no problem. I have a 8350 running 5.2GHz 24/7 and at load has pulled on excess of 400w , so it's more than capable. I can also run 5.3GHz stable and bench some at 5.4GHz+ so the VRM is good on these and can handle it . I am more curious of the Rev 3.0 in the corner and what that entails.

I am with Ebduncan about the VRM spot fan blowing downward. It blows downward and spreads circulation to surrounding VRM components and get a better result than lifting the air off the VRM/NB heatsink. Mine never sees 40c @ 23 anbient.

Hurricane said that they are rated for 80C+ and I have been told the same from ASUS/Gigabyte, but It has been my observation like Hurricane that nothing good ever comes from running them that warm.

I stuck a Noctua pointing at the NB/VRM and noticed no difference in performance (on my UD3 there are no sensors for NB or VRM, but I can tell when it throttles and touch it and either burn myself or not). Only when I put a smaller fan blowing air on the VRM did I notice a difference. The fan I used, as stated above, is one of the frameless fans that came with my 7970. I just used self tapping screws to bolt it directly to the VRM cooler. I can now touch it without burning myself, if I can manage to get my finger around the fan without losing it.

The only WB I can find that will fit this board is this at ppc. The UD7 has a different layout.

Well what raised an eyebrow what that picture is they're pitching this apparently as a revision & re-launching of the currently discontinued UD7... and with the cutback to UD4 grade hardware as opposed to the UD5 grade hardware that the original UD7 board had on it. While no one knows exactly what the rumored FX-9000 is, some have speculated that it might be a 10-core Vishera revised and boosted up to 5GHz, some have said it might merely be highly binned 8350s that come factory locked to 5GHz, some are speculating that it's an in-between tweak/revision from Vishera to Steamroller with it's own unique, though very Piledriver similar die and could be kind of a precursor to the architecture we'll see when the Steamrollers launch, etc. All that's concretely known from the current info is a 5GHz FX CPU with a scorching TDP of 220W... which leads me to think it's AMD sort of testing the waters about launching a high performance enthusiast line. Which would be great to see if they do it right. I'd not have a problem paying an extra $100-200 for a FX that gives the buyer an extra 15-25% performance over the mainstream line of CPUs, even if it means I'd have to spend another $500 or so putting it and a GPU under a full custom water loop to keep it from cooking.

I know we're most specifically talking about VRM, capacitors, and the like here along with probably a voltage boost to the HTT, so why down grade the components that specifically handle power consumption and regulation? The idea that they're taking lower quality hardware to put on a board that is being re-engineered and tweaked "specifically" for the most power hungry FX series CPU we've seen yet seems kind of foolish to me... like Gigabyte is just setting up anyone who wants that board and chip to fail. If the original UD7 boards could easily handle that kind of power load, why not leave them be or even beef them up a little more?

After all, Gigabyte already has a lot of issues they're ignoring with the 990FXA-UD3s, and this makes me question just how good the new rev of the UD5 and UD7 for these beefier FX-series CPUs will end up being.

I had read on here that some one has tried the same water blocks but it would not fit, but if it does i would be happy because i have some custom water loop in my mind any time soon thumb.gif

Also i noticed that the CPU voltage and CPU cooler has a great deal with vrm temps because i had mine to 5ghz stable at 1.6 volts and my CPUNB to 2570 and set the NB voltage to 1.200 and the offset to +225 so the voltage was 1.4125 and it was getting very very hot exceeds 70c and becomes very unstable.

So i lowered my OC from 5ghz to 4.6 with 1.48 volt and the HT link at 2826 and CPUNB 2570 with the same amount of volts it is significantly cooler, like 51c was the max i ever saw on it.

So my conclusion is that IF you want high OC with high CPUNB and HT link you need an very very good cooler to keep it cool because anything above 4.6/4.8 needs so much voltage and dissipates so much heat that the only thing to achieve that with low temps is an way overkill custom loop cooler and if you want it to last any long than would an motherboard water block kit be advised thumb.gif

That seems to be par for the course with Gigabyte's 990FXA boards... I have a friend who uses an ASUS Crosshair for his 8350 @ 4.9 GHz and similar NB/HTT to yours on air/water cooling (H110 for the CPU, air for everything else) he never sees boards temps above 60c... I think in part it has something to do partially with the airflow inside you tower and also with the engineering and design of the board... ASUS ROG boards seem to be extremely well designed for OCs and high performance use, and Gigabyte just seems to not be at all focused on making a strictly gaming/enthusiast line of boards, at least not for AMD CPUs.

It could also just simply be that the UD7 on the display there is just a prop or placeholder for a board/revision that has not even been manufactured as of yet. To many unknowns and scenarios to say at this point.
BTW, the original UD7 and the subsequent rev 1.1 was actually UD3, not UD5. If you expand the image you can see the' Ultra Durable 3" Low RDS Driver MOSFET package. trust me on this, i own one of each smile.gif
