Changing the Heatsink on a SAS expander card?

Hey, was not sure where to post this but i thought the cooling section might be the best :)

I have a Chenbro CK23601 however the little fan / heatsink on it is noisy all the time. I was reading the Hard forum and someone replaced it with a large passive northbridge cooler. I was wondering if anyone could help with how you would do this?

I replaced the stock heat-sink+fan with a large passive North-bridge cooler.

Runs much cooler and noiseless. Stuck a thermistor onto it and the temperature hovers around 30 deg Celsius with an ambient temperature of about 26 Deg Celsius.

Pictures of the card so you can see the heatsink / hole positioning :)

Thanks! :)
 
That looks great! I just need to check the clearance of the bottom of the case. The side of the case has a 120mm fan blowing on the PCI slots so a passive cooler will get lots of airflow and will be fine id imagine?

Thanks again.
 
Sorry for the double post, just wondering if others agree that that heatsink is ok or i should look at another (before i pull the trigger) :)
 
Don't see why it should be a problem if you can fit it in the space. My intel RES2sv240 expander and the HP expander are both passive and rely on ambient airflow to keep them cool. (most people actually add fans to them)
 
I dont seem to actually be able to find this except for one for £28 ish pound. Which is a bit more than i wanted to pay :P Does anyone know of any alternatives. Thanks! :)
 
Just an update i got a "Xilence Cooler Northbridge Heatsink" and it fits perfectly :)

Tidy job. That ought to do a better job than the original. Question is, will the expander report fan failures to the HBA and fill your logs up.
 
I have checked event viewer and cannot see any logs regarding fan's or anything like that. I actually did not even connect the fan to the expander's fan pin as it didnt fit (Expander requires 2 pin fan connector but it had 3 pins) so i just connected it to a molex. Everything seems to be running fine.

Was there somewhere specific i should be looking for the fan failure in the logs and ill have a look :)
Thanks.

Funnily after cleaning all the thermal paste off the chip underneath that it is cooling is an LSI ARM lol :P
 
With an LSI HBA, you just connect to the machine using megaraid storage manager and it displays the log in the lower section of the window. It may not display anything if it's not designed to monitor it. My intel expander reports sense errors as there are no backplane temperature sensors connected IIRC.
