W860CU - Fan CPU problems

About 3 months ago I bought a W860CU barebones for RJtech and I used my 720Qm CPU and 2 x DDR3 4Gb with a Samsung 256Gb SSD

Since I was away on some business I didn’t get to the machine until a few weeks later
However I started to notice lockups and BSOD when I was installing the O/S (not a good sign)

Basically I have noted this:-

1) The CPU fan doesn’t turn on and the CPU will reach 100c since no fan this happens in the bois/setup screen as well as windows
2) On CpuID it reports the ACPI temp TZ_ as 0C but the CPU temps are reported
3) If the slow fan button is pressed the CPU fan will spin up and cool the system

I reported all this to RJtech and told to ship the unit back ( I shipped with the all parts so that It could be tested together)

So about 2 weeks later and 250 bucks in shipping, it was back with a new motherboard
CpuID reported the ACPI temp fine

I reinstalled Windows 7 and everything was fine until last week and I started to have the same lock-ups and BSODs reinstalled CPUID and the ACPI_Temp was 0c again!!

The issue is that every time that I send the machine back to RJtech it costs me 250 USD for the shipping both ways

This machine is rapidly turning into a lemon

Any suggestions ?

 

Check if the fan is working properly.
Also, use other monitoring software, like HWinfo32, Everest, etc, to see if your system is indeed overheating.
To me it looks like a fan issue (either a faulty fan or manually slowed down by you pressing the "slow fan" key? I'd keep it on max setting if it's possible)

 

The fans are fine I swapped the GPU one with the CPU one and still have the issue

 

I suggest you run memtest86 to see if maybe fault memory is causing
the problems, and maybe install a linux distro to rule out a bad copy of windows, also do you have a regular HDD wdc or seagate to rule out a bad ssd

 

Can you run HWinfo32 and post a screenshot of the sensors menu after running something heavy for a few minutes?

 

$250? Where do you live, Singapore?

 

Close Japan..

 

Here's the HWinfo32

Japan? Cool.

Unless you are using a cryogenic cooling system -.2 is pretty much impossible.

HWinfo32 is able to read the Clevo EC correctly, I've corresponded with the author of the software directly about this, so from my limited experience and your symptoms, it seems like your EC thermal sensor is busted. If your Clevo is anything like mine then the EC CPU temp is used by the system to set the CPU fan speed. If your EC CPU sensor is busted and reading sub-zero then your fan is most likely not kicking on at all, causing your CPU to overheat. Unfortunately, if its your EC there is no simple solution since the EC is integrated into the motherboard.

My best suggestion, depending on how good you are with a screwdriver, would be to send a screenshot like that to RJTech and ask them to cross-ship you a new motherboard instead of having you send the system to them. If the only solution is putting in a new MB there's no reason for you to have to send it since the solution isn't going to change, unless you don't want to do it yourself.

Best of luck with your situation.

 

^^ That's a good advice! Do it and good luck this time around!

 

I'm a server engineer so it's not a problem to swap the board I did ask this the last time but RJTech wouldn't ship just a mainboard to me.
Unless this is a common problem two boards with the same strange fault is ringing my engineer alarm bells but there not much left after you take the main board out of this machine

It would be nice to speak to someone that does the board repair on these machines

 

Have you made sure both parts of your firmware are up to date. Also two faults like that almost would make me think they did not replace the board. Maybe they got it to work on their end and did not replace the board.

 

The guys at RJTech don't seem unapproachable, give them a ring and ask to speak to the guy who handled your last repair.

 

The Rjtech guys are ok they are always quick to reply to emails but it's the shipping is going to kill me ..

They are saying it maybe the CPU but I'm not so sure the CPU temps works you can see it in the picture .. and CPUs tend to be working ok or very dead no middle ground

 

I thought that too but the mainboard's date sticker don't match with the rest of the systems
