LSI Megaraid 9280-24i4e Temp questions

[Culbrelai]

So, I have this adapter and a LSI 9211-8i. I have heard that the 9211 has issues with overheating in non-server cases. Does the 9280-24i4e have these issues as well? It has a much more significant heatsink.
I do know you can mcguyver 40mm fans onto the 9211 to make it have acceptable temps, but i’d rather… not. Small fans generally sound awful especially in a desktop case that’ll be near me.

any advice? Thx

I suspect that any fanless adapter like this will have overheating issues in a desktop unless supplementary air flow is provided.

I have an 120mm fan blowing directly down onto my HBA in one case, and an 120mm fan leaning on the side of the HBA in another to solve the problem with minimal noise.

If anything, I suspect the 9280-24i4e is going to have higher cooling requirements as it has a SAS expander chip (SAS 2x36) onboard to enable that many connections to the SAS2108 RoC. So both of those are going to generate heat. The SAS2008 on the 9211-8i consumes between 7-8W, but has a tiny heatsink. So you need to dissipate that heat or it saturates that tiny heatsink and the temps will keep rising until something fails.

The only LSI/Broadcom SAS controllers that I think can go without any air are the 1st generation SAS1068 cards, but those are mostly obsolete. The SAS2008 (on the 9211-8i) is actually one of the cooler running cards, as the following 2 generations just keep getting hotter. Broadcom started improving the power consumption around the 9400-8i, and furthermore on the 9500-8i. So, if you want very low cooling requirements, the 9211-8i or the 9500-8i are the better choices, but neither should be 100% passively cooled.

I had to point a fan towards my 9XXX series controller. I just used a spare 120mm nocuta case fan I had and zip tied it to the case back through one of the pass-through holes for cable management and had it pointed/aimed towards the heatsink side of the controller. It really didn't take much, it just needed some airflow (this was in a Fractal Design Define 7XL case).

Edit: Also, that was with the 3 stock fans that are only 68.4 CFM each (2 intake, 1 output). I am currently in the process of replacing those 3 fans with Noctua NF-A14 iPPC-3000, which are 158.5 CFM each, but that is a task I was waiting for my holiday break in a couple weeks to tackle (along with a PSU upgrade).

Thanks for the advice everyone. I have a laser thermometer I've been using to check the heatsink, its at about 36c while doing a simple file copy. I dont think there is a way to actually check the temperatures from within windows is there?

I wonder if these errors are temperature related...



Honestly, I think its time to upgrade. Just bought an HP 240, it seems to have much better software/diagnostic support than this old LSI. Also is faster. And it was super cheap, lol.

Not sure about in windows for checking temps other than with command line from lsiutil....
