Heatsink Dimension Issues

[elproducto]

First time posting so I'm not sure if this is the correct location.

I recently built a computer and I'm looking to install an aftermarket heatsink since the one that came with my CPU isn't doing a great job.

My motherboard is the Biostar TZ77B and there's very limited room. I measured and it looks to be about 101mm x 126mm x 152mm. I'm not sure exactly how the dimensions are specified with a heatsink but if you took the side off of my PC and looked at it, the 101 is from left to right, the 126 is top to bottom and the 152 is in to out.

I asked Biostar if i can switch my RAM to the a2, b2 slots but I haven't gotten a response but that would give an extra 12mm. My CPU is the Intel Core i3-2120 Sandy Bridge 3.3GHz LGA 1155.

I'm struggling to find a heatsink that can fit those dimensions and is highly recommended. Can anyone give me any suggestions? Thank you for your help.

Works like a charm! Reduced my idle temp's to 28-32 Celsius. I changed the BIOS to "Quiet" CPU fan setting. I played BF3 on the highest settings and it peaked at around 50 and the CPU fan never engaged into it's higher setting. Should i be concerned or is this okay? The higher setting on the CPU fan is pretty loud but the low is great.
