FX-6100 Zambezi Woes

post #1 of 9
Thread Starter 
Greetings all smile.gif

I'm having some issues on a new build.

I'm running an FX-6100 Zambezi on a Asus M5A78L-M/USB3 (latest 0801 bios) and experiencing some unexpected temperature variance.

Currently for safety's sake the CPU is running at stock 3.3ghz @ 1.2625v (I just copied the VID since I cannot find a specific voltage setting for this processor anywhere).

I'm using a Scythe Mugen 2 cooler and the temperature is reading 21c idle, yet 58c whilst running prime95.

A simple 3.7ghz oc at 1.3v changed that to around 29c/64c. When I turn the load off the temp drops ultra fast, so I'm somewhat perplexed. Letting the bios auto handle the CPU is suicide also, into the 70s.

Any advice gratefully received.

These processors put out a lot of heat when loaded up. I'll let the BD experts take over but i'll say thats pretty normal.

Are you sure Scythe Mugen 2 can handle 6 core cpus ? I stand corrected, just checked it and even if it's not a Core Contact type, it should handle a 6 core with those pipes.

Maybe bad TIM or apply. Did you reseat the cooler ? If you do, check how the TIM spread. Pictures would be good biggrin.gif

Thanks, I'll try another reseat.

Put a better fan on it if you can. Scythe's fans are usually really low rpm and will perform badly.

Try one of these...

or one of these.

Mugen 2 should be performing much better than that. Do a reseat and reapply thermal paste. While the Mugen 2 is an epic cooler (I had one with two FM-121 in push/pull and WOW), the mounting system is pretty bad and it can be hard to get a good seat on it.

I'd also say seating.

Usually high temperature variances would be lack of heat capacity in your solution. A CPU of that caliber cannot heat up the surface area of that cooler that quickly, unless it is not making sufficient contact, whereas the CPU will heat up primarily without having the ability to sufficiently transfer it's energy to the rest of the HS.

Yep, problem solved.

I gave it a fresh schmear of artic silver and was a little more forceful and meticulous with the screws. I'm the heavy handed type and I think i maybe over-compensated smile.gif

When I got it back in it was idling at 11c and full loading at 28C...

Many thanks for all your time.

Now to nurse my build lacerations..

Hmm yes, lack of pressure can also build air pockets in-between TIM. Also struggling too much and too long to seat it on the cpu. That reminded me of reseating the Thuban cooler on my old x2 5600 lol. It's 45 idle 55 load without Cool'n'Quiet :/
