- Small VGA ram heatsinks: Zalman ZM-RHS1.
I've placed two of them on the chip in the middle.

- Thermal paste: Artic Cooling MX-2.

Enzotech heatsink + Thermal paste


Polished surface


Zalman heatsinks


Enzotech heatsink attached


My low rpm 120mm fan in the sidepanel of my case wasn't enough to keep the heatsink cool, so i've attached a small fan to the heatsink with tie-raps.
Now i can touch the heatsink longer then 10secs.

I hope it keeps cool enough when i connect some drives in raid5...
You only need TIM to get the heatsinks to stay put?

I plan on using the southbridge heatsink on the chip in the center. Does that black heatsink really need upgrading?

Whats the chance this card will work in a PCIe x 1 slot.

I understand if it works then it will run slower however only looking for 100meg/sec

It theoretically should work fine if your x1 slot has a notched end or if you get a pci-e x1 riser card with a notched end. I'm not sure about power requirements though. The x1 slot may not have enough juice to power the card.

The bandwidth limitations per lane of PCI-E are as follows:

v1.x: 250 MB/s
v2.0: 500 MB/s

This is an upper limit (maximum speed), actual transfer speeds may vary.

After you're done you can flash it back to the LSI firmware. The flashing doesn't make any changes like losing your RAID configurations.
You can actually use the 9.0.1-0034 (APP_1.20.32-0512) firmware from the LSI archive to flash it, then you'll still have the boot manager.

Hi, thanks for noting that. I checked the archives but that's quite some versions older than the most recent one. Also looking at the release notes of all versions after the one you're mentioning I'm wondering if it would be wise to use it. Are you using it? Because from the looks of it you'll miss a lot of features but also critical performance enhancements and bug fixes with that older firmware.

Anybody got any answers regarding the SCT part?

Has anyone had success flashing the firmware from within Win7 x64?

Also, the clipping mechanism on this HSF looks similar to the OE one:

Remember that the PERCs are PCIe v1.x cards - even used in a v2.0 slot, they will still only be able to use 250MB/s/lane.

It might fit (not really bothered to check).

However I would be a little wary as to whether such a tightly finned heatsink would do well in free air. I suspect it would give amazing performance with a 40mm fan strapped to it, but if you rely on unforced convection with that heatsink you will probably get little better performance than with the stock one.

A slightly taller or wider heatsink would be better IMO.

The clipping method is the same but not the right size. That's 2" in diameter... I believe the card's loop mounts are 1.5" apart?
Once again...

When someone says 250 MB/s

are they saying

250 Million Bits
250 Mega (1024) Bits
250 Million Bytes
250 Mega (1024) Bytes

Can someone confirm that
m = 1,000,000
M = 1,048,576 (1024 x 1024)
B = Bytes (8 bits)
b = Bits
