me 850 watter and a cheapo twer cooler and started getting issues....voltages look ok..then its gotta be the tower cooler..looks like the mobo made good use of the stock coolers airflow to cool the heatpipe...hmm...better pop a 120 to blow on it fast!!!
that or me seniled and dun remember oc settings

add a couple 120mm fans overhead to drop temps by 10+ celsiusD.S.C-12(2)-
dont think its heat man..well it is but not for cpu....its for mobo components i think..the present cooler will not blow any air on them lol....gotta rearange or go back to stock..........
hate noisy mobos, love silent ones but ....
and the 120 i already did but dont have an elegant solution for it atm...or if you were talking about thermalright's 120 then nono...the OCZ Vendetta 2
Shouldn't be. Y have a tower cooler blowing out the rear of the case and more case fans than a tree full of woodpeckers. Sumptin ain't right wit the airflow patterns er sumptin.
Can happen with Psu's sometimes too, your shiny new one may (probably does if it's the TX850) have better regulation control than the one you replaced, especially on the 12V rail, that could lose you a few hundred millivolts on the Cpu vcore if it's set manually....
"possible"....

I can't see that causing the heat problems he's describing through. A PSU would have to be pretty messed up to cause that. Ask him if he smells fried chicken emanating form it

was thinking about that but what makes more sense is the lack of airflow around the socket area, important on me passively cooled mobo i guess..
edit yes its set manually. before id see it move now its quite stable.more like a straight line lol. i nly have one g80 in there too, stock e5300....have probably another 600 watts to spare
edit7 lookie.havent seen this in many consumer psus before.. :

thats theoretical, but it is probably indeed heat thats doing the doodoo
no fried chickedn, quieter than a lot of psus ive had so far. exaust smells...well..nice

I hate to say this Ken but that's not true. The whole reason why the core supply/regulator runs off the +12v line is to isolate actual core variations from 12 fluctuations. Remember that according to the official PSU standard, +12 can have up +/-50 v P-P noise/ripple, 250 mv under some conditions. The easiest way to eliminate that at CPU level is to make the core regulator deliver from a much higher source, and that's what 99.99% of all motherboards do. That and of course the difference in power derivation type. One is a whole lot cheaper to get than the other

Well you know what I meant by fried chicken LOL. At least we agree on heat. Not too unusual for mass market production parts to have a few get through QA/QC (if they have it) without being tested for temp coefficient. My left nut would fall off if they did. So yes, more likely the mobo IMHO. I'd like to see that PSU on a scope under a dynamic load test though, even though as I explained to Ken, just tain't likely to be the cause.
I kid you not on one other little point. Giga mobos are among the best out there, I think we agree. BUT there ARE those floating around out there that have a nasty habit of getting unstable because of unbalanced power distribution, caused by improper grounding, which the mobo mounting screws very definitely effect!!!!!!! How many people dou you think, consider that, eh?
Well now, his reviews are slowly improving. That's good. The PSU looks good, bottom of the PCP comments, are not appropriate, with the exception of that corner with what looked some of dried up goop on it. His pics of the scope noise traces are worthless because you can't see the vertical (amplitude) scale factor. He really has a lot more work to do to write a credible review, but the effort is there, being made. Just as our own Lee G did. That's good. I liked the generous heat sinking used in particular. There is one drawback to that physical design though, that is that the PSU components themselves don't get hardly any airflow over/around them. The reason is obvious, and it also compromises the PSU's ability to draw/force hot air out the rear. Just like anything else cooling, an obstructed intake isn't an effective one.
his comments are funny, im with you on the graph's scales and trust me i beat me head against the wall before settling for this one. so the heat sink part i forget.

Aha! It has worked, the unit's given everything away! I know where the 5V problem is! Dead center. Yes, folks, the unit is missing a 5V sense wire. This wire was present in the LS1000. You should add that to the LS1200 for BFG, Enhance. It's just one wire, and it brings the 5V regulation into much tighter control.
