Blade-server heatsink for HS22

This compact heatsink is built for the IBM HS22 blade server and carries part numbers 46C3545, 49Y0659 and 46C7320. It targets administrators who need a direct-replacement cooler for a single processor socket in that platform. The unit is sold new despite the supplier noting a used-but-working reference. Buyers looking for a cooler for any other server or desktop platform cannot use this part.

Fits the HS22 blade chassis slot

The cooler mounts directly onto the processor inside the HS22 blade enclosure, using the existing retention mechanism. No additional brackets, fans or cabling are required beyond what the blade already provides. It occupies the standard low-profile space allocated for the CPU thermal solution. Builders working with rack-mount or tower servers will find the mounting pattern incompatible.

Passive fin stack relies on blade airflow

The aluminium fin block measures 11 by 7.6 by 2 centimetres and has no integrated fan. Cooling performance depends entirely on the high-velocity airflow generated by the HS22 chassis fans. Under normal blade operation the assembly runs silently because it adds no moving parts. Power draw is negligible as the component is purely conductive. Environments with reduced chassis fan speeds may see higher processor temperatures.

Questions about this item

What thermal limit appears first when the 11*7.6*2CM heatsink runs continuously in a blade server?

The compact 11*7.6*2CM profile limits heat capacity, so the fin stack saturates quickly under sustained load and the CPU hits its throttle point before the fan reaches maximum speed.

How much noise and heat does the 46C3545 heatsink add when the HS22 blade runs all day?

The heatsink itself is passive and silent; all audible noise and exhaust heat come from the server's system fans, which ramp up as the small 2 CM fin height fills with heat during extended operation.

Which server chassis and mounting hardware must I already have to install the 46C3545 heatsink?

You need an IBM BladeCenter HS22 bay with the correct processor retention bracket and thermal interface material, because the 46C3545 is shaped specifically for that blade's socket and mounting pattern.
