PERC 5/i RAID Card: Tips and Benchmarks - Page 509

post #5081 of 7188

Just checked and even the mini-SAS cables I ordered from cross-mark.com don't work. I have a LSI 8308ELP that I had to hot-knife cut the power section off the cable ends years ago (since the drives are in a hotswap backplane that uses molex power).

See Image:



I wanted to pretty up my cables so I bought Cross-Mark "80cm Mini SAS to 4 x SATA Data Cable". With their cables the drives are unavailible on my LSI 8308elp. So I re-plugged in my old hacked cables and boom availible. Things are not looking good for cross-mark.com

All I want is Raid 6 so I don't have to worry about a 2-drive failure again. My 8308elp is a plenty fast card, but Raid 6 is the whole reason I bought the Perc 6/i to retire my 8308elp.

So I bought these cables now:


I sure hope they know what the heck their doing.

P.S. once I get this all figured out anybody want my 8308elp. It's basically a perc 5/i with two sff-8087 instead of two sff-8484. Plus it has the additional audible alarm and hdd led pinout header.

Which software do you people use on the Windows-platform to monitor the Temperatures on the chipset(s) on the Dell PERC 5/i?

I don't believe the processor on the PERC 5/i has a temperature sensor...

Hm, alrighty.

Also, I'm swapping the cooling on my card, would it be enough to mount a 40mm fan on the heatsink, and just add a heatsink to the cpu that doesnt have one, or wouldnt it be enough?

Also, how the **** do you remove the mountingclips on the original heatsink? ;P

No need to add anything to the other chip - it doesn't get hot.

A small 40mm fan would be more than enough - decent airflow in the area is sufficient.

Stick a small screwdriver in the slot holding the wire clip in place, and gently wiggle it a little to move the tabs holding the clip in place. It will fall right out easily.

Hm, alrighty, so I shouldnt bother with adding cooling to the other chip at all?

So basicly, just add the 40mm fan to the existing heatsink and I should be fine?

Also, a question, would it be sufficient enough to have the flow direction AWAY from the heatsink, or do I need to have the fan flow direction ONTO the heatsink.

I am pondering over ways to attach the 40mm fan to the heatsink but I seem to only have 1 solution, that includes the flow direction to be away from the heatsink, but I'm not sure it will cool the chipset enough.

What's important is airflow over the heatsink. You can have the fan anywhere, but be aware that the flow patterns upstream of the fan are (usually) very disfuse - so you won't pull much air from over the heatsink itself unless the fan is very close to it.

Is a duct an option? If so you can pull enough airflow directly over the card with the fan some distance away. However with this option you also need to be careful not to block other components from direct airflow - the other chips & regulators on the PERCs, but also your SB etc that may be blocked by the ductwork (or even the fan itself).

I was planning to have the fan directly on the heatsink, but I've only found 1 way to attach the fan to the heatsink, and with that way it means the fan flow direction would be away from the heatsink, but yeah, it would be right ontop of the HS.

Ah well, all is good, I managed, with a few altercations, to fit the 40mm ontop of the heatsink.

So it should be fine now I suppose, I shouldnt be worried about the temp anymore?
