[First Look] DFI 680i LT NF-680i LT SLI (56K Warning~~~)

question
How hot is too hot for the NB on this board? Virtualrain, it seems youre NB is running somewhere between 40 and 50c, what are you cooling your NB with? Past 440fsb I need to crank up NBv to 1.6v or better, results in my NB running at approx 80c I don't like that..

I am going to try to re-arrange my rig a little, the ultra120 extreme with 2x 120mm and 2x8600gt vid cards it gets a little cramped and can't get a fan on the NB... holding a fan pointed in the general direction of the nb drops it to approx 75c.. still too hot for me, but better.

Wow... that seems way high... Perhaps try remounting the NB sink.

I just have a basic 120mm fan leaning up against the NB cooler. I guess it's pretty effective since it cools the top and base together. I'm working with it open on the bench though so that helps as well. I'll be water cooling it when it eventually goes in the case.

And the vid card with that fan sitting like that

And the vid card with that fan sitting like that

LOL! The fan is not touching the video card but even if it was, it's not a problem (a) because the fan is plastic and (b) the video card is a POS!

I'm just using a POS MX4000 PCI video card for the bench setup since I want to keep my old system up and running until I'm satisfied with the OC and ready to mount it all in the case. I work at home so I can't afford any down time and it's also why I'm a bit more of a prime-stable fanatic I guess.

Thats it, I'm pulling it all apart tomorrow night, cleaning all the surfaces and trying some different paste.

NB temp was at 50c for 3 hrs of prime, then shot up to 70c and seems that the NB HS is not completely stable on the chipset, if i push on it a lil the temp drops, I would say its a bad mount, how about that foam tape on the board and HS, is it necessary to have on there for stabillity? I'm thinking about taking it off for a tighter seat.

there's a thread about this on dficlub...

I've a solution for the PWMs:

Wait about a few days, MIPS-Computers is producing new PWM-Coolers for the DFI board!

They design a new NB Cooler, too. The Intel Freezer for the Bad Axe Board does not fit well.

results in my NB running at approx 80c I don't like that..

holy croaks ! !? ! !! ! ! i would shut that thing off quick if i was hitting 80c. i can't believe it's even working at those temps. raja recommends the NB temps not go high than something like 48-50c and you are well past that.. wow.

do you mind posting pics of your MB with the ultra extreme mounted ? i'd like to see what kinda space you're dealing with. i have an ultra in the mail so i'll be going down that same road soon.

Don't laugh

sryy about the crude drawing, this is the best I can think of right now, with both fans pushing air into the HS, it creates good airflow through the NB HS, 5c higher cpu core temp vs one pushing and the other pulling, under load at 3.5GHz, No good.
I re-seated the NB HS and temps have dropped approx 30c down to 48-53c, much better :P
I will post some pics later, have to go get the kids...

BTW, I was running orthos for 1.5hrs with FSB@440, NB@80c, no issues, scary? yes...

Sounds like a bad mount to me. Mine doesnt go over 45c or so

I have run into a new issue however.


It seems CPU throttling is somehow tied to VRM temps. Even with the CPU under 65c in core temp, the CPU starts to throttle its self. This is on water.

Once I place active cooling on the VRM it stops, take it away and it starts right back up.

Still trying to figure out what would be an effective VRM cooling solution over stock.

lol that makes two of us... let me know if ya come up with anything

i don't understand your drawing... where do you have fans and where are they blowing ??

Put me in the throttling category, having the same problem. I'm running on air though and have a cooling fan over the VRM. If you look at page 88 of your manual you'll see the options in that screenshot for thermal management but seems like with this bios we dont have that option now?

What are the symptoms of throttling? How can you tell it's throttling?
