error code 3700:011b on both fans

Did you check to see that the two fans and the air temp sensor are all properly plugged to the correct connectors on the motherboard? See page 60, here.

Dell fans typically have a sensor in them that's detected by BIOS. If the sensor fails you'd get fan failure errors.

I removed and blew out (air can) the processor cooling unit and the associated fan. didn't see any other fan in the box.  Except for the fan in the PSU. also removed and replugged the thermal sensor.

I know the manual talks about a "card fan" but the bios refers and errors to a "rear fan" ? didn't see either.

machine sounds a bit lower now, still noisey, seems to work ok, but still shows the same POST errors.

Also, while I have someone's attention, is there any way to run the dell web based diags on ubuntu? Tried it with wine, but it seems to hang on what looks like an older version of internet explorer.

Thanx,

It certainly is confusing. :emotion-7:

The motherboard schematic in the manual shows a connector for a "rear fan" but there's only instructions to install / remove a "card fan" which appears to be located below the power button on front of the tower in another drawing.

Don't know if the "card fan" was an option, but if it's missing, I wonder if that's causing the boot error for the "rear fan"?

Did you try resetting BIOS to the defaults to see if that will clear the fan errors? Be sure to copy down all current BIOS settings before removing the motherboard battery so you can change things back appropriately if the default settings don't work when you  reboot.

I would be careful about possible overheating if the fans aren't working ok, especially if the CPU fan isn't working properly. Note that on some Dell systems if the  video driver is missing or corrupted, that can cause the fans to go into overdrive. So make sure you have the right driver.

Doubt the web diagnostics will run with Ubuntu. But if you have the original Dell Resources disk, it should have the diagnostics on it. The disk is bootable so independent of whatever OS is on the hard drive.

Yeah, I didn't get any disks with the sys. just the box itself. maybe the resource disk is downloadable?

Yeah, but this isn't the case, i'm hearing the fan(s) slowly escalate on power up, and then just stay up there. I thought I had it isolated to the video card and blew that one out, but it's still the same.

I tried the cmos reset via the jumper, and that doesn't seem to be it. The errors are the same: the 2 fans and the thermal sensor. I've done this before, but i can't figure out how to get the battery out (my eyesight ain't what it used to be either ;( ) 

So, am I back to replacing these parts? And where can I get them inexpensively? This project is turning out to be expensive after all.

The fans slowly speeding up is typical of either a bad battery or corrupted video driver...

Look at page 37 in the manual for info about removing the battery. There's a small tab that you have to gently push away from the battery so that it will be released. Use your fingernail to pop the battery up while you hold that tab with the other hand. And this is probably a good time to install a new battery, CR2032 3-volt lithium ion battery, ~$2 at discount stores.

There's a heatsink+fan for $15 and case fan for $19 here for D9200.

Case fans here for ~$8-$10.

Don't think the diagnostics are downloadable, but look around on eBay for the disk. Or if you know anyone else who has a Dell PC, you should be able to use their Resources disk to run the diagnostics.

EDIT: Forum doesn't seem to like that hyperlink. So work through their 'tree' to find the D9200, here: http://www.discountelectronics.com/home

I guess you have to get new fans...
