9NDA3+ and Mach 11 GT Temps

[M8tRiX]

Hi All,

I need to solve an issue with temparture readings on the Epox 9NDA3+.

Specs :

1 x Mach 11 GT
1 x FX55 Stock Settings
2 x GSkill PC3200/PC4400 1GB
1 x OCZ Powerstream PSU

The evaporator stays at a -60 but the cpu is 26*c, when i run prime it goes up 3-4*c and when prime finishs the cpu temp drops back down too 26*c and during that time the evaporator temp is still -60.

I have remounted the brackets with fresh seal string and the evaporator head also.

Could the Epox mobo be reporting false temps or the Epox not read temps below o*c ?

Many Thanks,

M8tRiX. :banana:

Bad evap contact! Tor the kit appart and make your own mounting bracket. Much easier and way better :)

Hi bias_hjorth,

Thanks for the reply.

Apart from making my own brackets could i remove the metal washers (3 in total) on the evaporator screws and just leave the rubber one to get better contact ?

Many Thanks,

Yes you could do that. I actually had the same problem with the original mounting kit and tried various methods but neither worked so I ended up with using my own :)

you'll get better contact by adding washers actually, removing them will make you have much worse contact

Hi,

Right i have just noticed the top bracket has 4 feet on the underside ( one in each corner), could i sand those down and keep the washers ? These feet are 3mm in hieght. i think these feet are the problem because if you think about it, when you have screwed the brackets together the seal string compresses and the next point of contact for the top bracket is the feet and it could be these feet are not allowing proper contact for the evap head on the cpu.

If i sand the feet off the bracket, the bracket would then be flush with mobo and not the feet and i could achieve proper evap head contact with the cpu.

Am i going in the right direction ?

Many Thanks,

1600 posts and your answer has to be the simplest one and that is he "MUST" have bad contact and not even consider the issues 99% of users have with temp's on nf3-nf4 boards with alot of 939 chips.

Your temps are higher IMO and or do not change becasue there is either a issue with the nf3-nf4 boards and the reader used to read the on-die thermal diode or the actual diodes amd are using are not calabrated right or vary in such a way that its becoming impossible for motherboard manuf. to read these temps correctly.

The CPU's themselves don't read temp's. The chip has two pins a + and - these are the leads to the diode in the manuf process the leads are not all the same not even close so the motherboards circuity that reads these temp has to calabrate this diode to read its temps acuratly and this is becoming alot more complex.


msi neo2
epox's 939 nf3
gigbayte's nf3 "both boards" with -70c temp's all read 36-40c and I've tested alot of boards and trust me I have some of the best contact you could ask for.

Bottom line iis f you go sub ambeint drill a hole in the base of the block or get a sensor stuck on the IHS and read temps that way..

I never knew there was a Mach 11, I thought there was just the Mach II and Mach I.

LOL, yea...I know you're joking...but...wait.....are you joking? :P

I get the same thing with my Asus A8V Deluxe mate.

Mach II GT reads, -57.c yet the Asus Probe and BIOS read +56.c

However if you go into the bios as soon as the Mach II GT is turned on, you can watch the temp drop to -18.c before it magically jumps to +50.c and then hovers there for ages

to test contact... put Arctic Ceramique on the CPU and then screw the head doen.. when you remove it the evap head should be white too! Give it a try... worked for me! ;)

Hi Cachman,

lo m8 from EP-UK forums,

Well you are right but there is a fatal flaw in the bottom bracket design. In that the bracket has little feet in each corner, solution sand them off

Two the holes for the bottom bracket are just that holes with no beveled edges for the screws, solution i made my own beveled edges and now the screws sit flush with bracket.

Now my cpu temps are 16-21c idle instead of 26c and the evap is -62, when i run prime i get a 2c raise in cpu temps and the evap head still at -62.

So i can only conclude is that the cpu diode cannot read the cpu temp below 0c and it seems i am not the only peep with the problem.

It's a MoBo problem.... can't deal with negative temps.... with a 3000+@3GHz/1.7V the MB reads +30C on the CPU.... yeah, right :)

You can tell if you have good or bad contact when you try overclocking.... you can't get high clocks if you have bad contact.... no matter what the temp reading says.... ;)

Matrix :)

Ello from EPUK too! Also, did you find that removing the little black feet actually helped? I noticed those feet and did think to myself that they "could" be higher that the round of Seal String that I put on there.. without them Im sure you will get a better seal... dunno if it'll make it impossible to remove tho?

Removing the feet helped by 7c lower in temps for me.
