LSI 9271-8i RAID controller used in a MicroATX build, good idea, or not?

post #1 of 6
Thread Starter 
Based on this concept I made of a build using the Rampage IV Gene motherboard with only four PCI Express slots:



...is it a good idea to sandwich an LSI 9271-8i like this? I was planning on using an Antec spot cool fan positioned near the PSU and angled it up towards the controller card.

If not, I'm considering ditching the LSI and just using two SSDs plugged into the motherboard and using the native X79 RAID. I'm thinking the LSI should really be used in scenarios where there's more airflow, i.e. >= ATX-sized motherboards where I can space out the cards more.

I don't know, opinions welcome.

well you could move the video card down to the other 16x slot and put the cards in the top 2 slots if you wanted too if your worried about heat issues but i would just use the onboard satas or onboard sound which ever you can live with out smile.gif

Do you really need the RAID controller?
on board is generally speaking fine for any non-server application.

This said, I've run an ARC-1222 directly below a GTX480, with an 8800GT below that, just had a fan in front of all the cards blowing air through them to the rear of the case.

I thought about moving the 690 down to slot #3 & 4, then put the LSI and sound card up in slot #1 & 2, makes positioning my Antec spot cool a bit trickier that way. I'm considering just using the X79 SATA ports (all two of them!), I mean in real life use, am I really going to see a speed difference of the LSI over the built-in X79 RAID? Hardly, I think.

I'm only considering it to create a giant drive to use for everything, installed apps, games, data, etc., with either 4 x 840 Pro's (256GB), or if X79 RAID, 2 x 840 Pro's (512GBs). I perform incremental backups weekly so I'm not concerned with a RAID 0 setup.

EDIT: Does that ARC-1222 cook like the LSI does? 90+ C isn't uncommon with the LSI, uncooled that is.

in case of RAID0, the speed difference would be negligible.

RAID controller only if using parity RAID.
I would suggest bottom slot only, also a side panel fan to exhaust the hot air or that lian li BS-03/06.
With a side panel 140mm fan my RAID controller is always below 60C even under load, the amount of heat coming out is rediculous.

I have my slots in this order.
