Firebaall Posted March 2, 2014 Share Posted March 2, 2014 Quick question: Most of the sensors that are reporting to iLo4, are pretty self-explanatory. Does anybody know exactly where the sensor 13-LOM is located? Is it at the broadcom IC towards the back righthand side of the motherboard? Link to comment Share on other sites More sharing options...
Dave Posted March 2, 2014 Share Posted March 2, 2014 Tweeted. Is there a PDF somewhere that offers locations? Link to comment Share on other sites More sharing options...
Firebaall Posted March 3, 2014 Author Share Posted March 3, 2014 I'd love to know if there was a PDF floating around. I haven't been able to find any documentation that tells me exactly where this zone is. Link to comment Share on other sites More sharing options...
oj88 Posted March 3, 2014 Share Posted March 3, 2014 LOM is LAN-On-Motherboard, right? So that should be the integrated LAN chipset, which is what the coordinate 12,12 points to on the board. The Gen8 specsheet says it's an HP 332i 1Gb 2-port ethernet adapter. I can't find any specifications of the 332i, but there's a PCI-E card that's designated the 332T. The 332T uses the BCM5720 and based on the datasheet from Broadcom, it has an internal temperature sensor. Link to comment Share on other sites More sharing options...
Firebaall Posted March 3, 2014 Author Share Posted March 3, 2014 Thanks, that confirms my suspicion of the Broadcom chip, being my target for one of those aftermarket chipset coolers. Network traffic is 24/7 on the server, so I'm not surprised by the extra heat here. Link to comment Share on other sites More sharing options...
Firebaall Posted March 8, 2014 Author Share Posted March 8, 2014 (edited) Just killing some time, waiting for the epoxy to cure..... I recieved part of the cooling gear I ordered last week. It included a box of Enzotech BMR-C1 heatsinks, and some arctic silver epoxy. The BMR-C1's are 14mm square which makes them almost a perfect fit for the 15mm broadcom chipset. There's a minute underlap in coverage, but the excess epoxy nicely bridges (as shown in the pics). I'll post some temps after the cure period. I'm hoping to see a few degrees shaved off the zone 13! I really recommend removing the 3m thermal tape, and going with the arctic silver epoxy. I believe it will hold up better, and transfer heat much more readily.

Firebaall Posted March 9, 2014 Author Share Posted March 9, 2014 Heh... I didn't have a clamp that would fit. Bamboo pencil sharpener and a full bottle of flux to the rescue! 1 Link to comment Share on other sites More sharing options...

Firebaall Posted March 9, 2014 Author Share Posted March 9, 2014 (edited) Oh, boy...did it work! 40 C under load! I shaved 19 degrees off that turkey! Edited March 9, 2014 by Firebaall 2 Link to comment Share on other sites More sharing options...
