Second fan in HP ML10 and new machine setup

Recommended Posts

I did check, the fan header is just a blank space on the ML10v2's motherboard.  There's other components missing, so I don't think soldering in another header is an option.  The HP fans are a 6-pin cable, I'm assuming it's PWM and another two wires for a temperature sensor.

 

I knew there was no fan header on the MB. I just received a couple of fans, a 60 and 80 cm Nonoxia Deep Silence models and I'll make one or both of them work on my next days off.

 

Thanks

I installed a 60cm with wire ties as suggested earlier over the remaining 3 pcie slots pointing right at the heatsink for the P222. I got a molex adaptor for power to the fan. As soon as I can figure out how to get back into iLO4 I'll check and see how the temps are doing. Don't know what happened to iLO but I get a time out in the browser now when trying to go to it.

A 60mm fan will make a difference (if it's really a 60cm fan you have in there you have to post a picture :) ) -- a picture would be nice even with a 60mm :)

 

Looking forward to hearing your results!

LOL... I'm originally from America, been here for 13 years now, and still have to get a ruler out to figure cm, mm, etc.

 

Had a hell of a time getting iLO to work again, but I finally got it running and the temp on the P222 is now 49c so a big difference from the original 84c. Well worth doing. I'll get a pic and post it in a bit.`

 

Cheers

Here is a screenshot of iLO/Temps after the fan addition...

 

Well, I tried to attach the jpg but kept getting The Server returned an error during the upload with both the Flash8 and basic uploaders.

 OK, let's see if this works. Images of fan, iLO temps, and the front of the server with the great little Icydock MB994IPO-3SB bay with Raid 1 WD Black 500GB drives and a half height DVD drive.

Sorry if those links don't work above, let me know, I think they are links directly into my account. LOL

The lack of a second fan connection is probably the reason.  I can't remember off-hand, and can't check until I get home this evening.

 

The P222 is probably lacking sufficient heatsinking for a low air movement case like the ML10v2 - it was probably designed to go in a high CFM rack server.  

 

I use a Supermicro SAS2LP HBA in my ML10v2, and it runs fine, but it's just a Marvell-based thing as far as I can remember.   Then again, I fitted a bigger heatsink to my M1015 - the heatsink I used is the chipset cooler off a deceased Dell Optiplex GX620.  It's just on there with some heat conductive epoxy and a 'safety' cable tie.

 

The P222 fits in the HP Microserver Gen8 and is a supported configuration.  I cannot see how the ML10 v2 would have less airflow than the Gen8; I would consider them at least comparable.

 

84C is not an unusual temperature.  They generally report 80-85C in an iLO4 on the Microserver Gen8, and they operate just fine that way; I've had mine in a Gen8 for 2 years now.

The ML10v2 has a large case with lots of holes in it, and only a 92mm fan.  Even with the plastic internal baffle, air leaks in everywhere, so the fan basically only changes the air in the case.  There's no real forced air at play at all.

 

The Microserver has a 120mm fan in a small case, and only air inlets at the front, so I'd say the Microserver has much, much better cooling.

 

 

My ML10v2's chipset temp sits at 48C, with ambient of 22C.  The top PCI-E zone sits at 42C, even without my Supermicro HBA.

The Microserver has a much more constrained chassis however.  Only so much air can be taken in, and the PCIe slot has no direct cooling from the chassis fan without modification due to where the exhaust fan is located.

 

I'd still think the P222 probably gets better cooling in the ML10 v2 case if only because there is more air.  The power supply also has a larger cooling fan (as opposed to the tiny one in the Microserver).  In the end, it may be a tossup.
