Problem with Chaintech 7NJL6 - startsup and then dies

UD,

I checked the fan, it seems to be sitting fine. The CPU has four cylindrical (i assume rubber like) raised surfaces on which the fan sits. It is a two wire fan. I did not get any thermal grease or anything with the fan. I bought all the parts (HD, CPU, MB, Memory etc.) from Tiger Direct. I have installed the memory and fan. Everything else is disconnected. I did clear the CMOS. It starts and then just dies. Maybe something is tripping it. I don't know. I have also sent an email to Chaintech. But no reply so far. This was yesterday.

Thank you so much for your help. Any other thoughts or suggestions. I am trying to get this up and running for my son. We are both very exicited about it. But so far no luck.

stop where you are! do not move or pass go! you don't want to burn up your chip.

you need some sort of thermal compound between the cpu and the heatsink base.

what heatsink do you have. can you give me a link?

some heatsinks come with a little pad on the bottom of them and has a peel off tape that portects it from dirt during shipping.

if there isn't one you can buy something like these listed at tigerdirect.

here is a link for instructions how to apply.

you may be able to find some locally.


your heat sink fan needs 3 wire. the yellow one is an rpm sensor which the motherboard looks for. it is a safety feature in case the fan stops.

again what heatsink and fan do you have? since it's not 3 wire makes me think the combo may be wrong.

UD,

Could the fan cause such a problem. I have posted the link for the fan that I bought

http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=412189&CatId=796 (http://www.tigerdirect.com/applications/SearchTools/item-details.asp?E...o=41218)

Below is the link for the motherboard that I purchased from tigerdirect

At this moment, I am just trying to narrow down the problem as to what might be wrong. I just want the board to work with bare minimum setup. Once this is done, then I will do the complete assembly for use. I will order the new fan and the thermal gel today or will go and buy one from the local store.

Thank you so much for all the help.

Regards,
Parm

here's one that's in the price range of the one you bought. if you notice it makes reference to a 3 pin connector.

* Fan Dimension: 66x60x10 mm
* Heatsink Dimension: 66x72.7x42.5 mm
* Rated Voltage: 12V
* Started Voltage: 5V
* Rated Current: 0.38A
* Power Input: 4.20W
* Max. Air Flow: 20.2 CFM
* Noise: 35 dBA
* Bearing Type: 1 Ball Bearing
* Life Expectation: 40,000 Hours
* Connector: 3 Pin
* Total Weight: 285 g
* Thermal Resistance: ca=0.58 C/W

how you managed to find one that only has 2 wires, we just chalk up to a $5 case of bad luck.

i use a single edge razor blade to spread the thermal compound. you don't need a lot. more isn't better. just smooth it out and cover the small die in the middle of the cpu. if you should get a little on the rest of the cpu, just clean it up with a q-tip and some alcohol.

keep intouch.

UD,

Thanks so much. I have also found something similar to what you have recommended at COMPUSA. It is a 3 pin connector and in stock. I can pick it up locally. Lets hope it works. I have the links below. Any input on these.

If they don't work, I will definitely order the one from tigerdirect.

I really appreciate all your time in helping me solving this problem. Once again, thanks.

the second one is much better. copper is always better. i don't think the first one is really rated for your cpu. it has much better cmf, 42 vs 9. if they don't have it in stock, i'm sure they can assist you in a good choice. they should have the thermal compound and a cooler for you at compusa to fit your needs.

UD,

I bought the fan and the heatsink today. It does not have the copper heat sink but something similar. It has three wire connector. It costs $14.99, I installed it and connected all the devices as well. But I get the same problem. Everything starts up but then dies after a few seconds.

I still have not heard from Chaintech. Tigerdirect want me to talk to Chaintech first. It could be the board. I know it is not shorting out. I will test the power supply tomorrow. This is the only thing left. I will keep you posted.

Thanks for all your help.

UD,

I just got an email from Chaintech. They are saying that the heat sink and the fan are not centered properly.

They asked me to check if the fan works without the CPU in the MB. I have three fan/heatsinks and they all work fine without the CPU. Chaintech said if that is that case then the CPU need to be replaced or the heat sink is not sitting tightly and properly on the CPU.

Any thoughts.

you did get some thermal compound also?


just to cover all the bases. the proper hs install:


Error: image could not be loaded. Image is not available from server

Image URL: http://www.thermaltake.com/images/coolers/volcano/1671/copperBase.jpg




if you placed the hs on the cpu with the large surface area on the cpu and the notched area over the raise portion where the lever hidges. the slot on the clip, where you put the screw driver, goes on that side too.

we haven't discussed the psu have we? on the side of the psu it should list how many amps the +12v. what does it say?

Hi UD,

I have bought the copper heatsink and the fan along with the thermal compound. Installed and everything seems to work fine. The system boots up now I am going through an installation process. I ran into some bios problems but they are fixed now.

This fan and heatsink is heavy and has a much better tension in the spring. This seems to have done the job.

I will keep you updated if something else comes up.

Thanks for all your help. I really appreciate it.

talk about a tough row to hoe, huh! this has been too much like work.

glad things are finally going your way.
