Heatsink Dimension Issues

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.

The clearances on that board are pretty standard, no reason the hyper 212 EVO shouldn't fit.

I'm seeing 120x80x159 which would line up to my space of 126 x 101 x 152? is 6mm enough room to fit that thing in? Thanks for your help (sorry if this is a bad question it's my first build)

Hello

If you look at the NewEgg customer feedback comments for your motherboard you'll find the Corsair Hyper 212+ or Hyper 212 Evo being mentioned as coolers that fit.
Including one with 16GB of RAM

What case case and RAM are you using? We can try and check those as well.


The layout would be like this:

The heatsink dimensions really have nothing to do with the motherboard, just to clear that up. The width (80) is all that really matters, but that's only for RAM clearance.

It should fit in that case, but RAM clearance may be an issue if one of the modules is in the slot nearest to the socket.

Your case is 7.68" and more NewEgg customer feedback for your case confirm the Hyper 212 sized coolers won't fit.

We'll look for something in 92mm sized fans which should fit fine.


Is your CORSAIR Vengeance the tall heatsink or the standard size heatsink?

It is and that was my biggest concern. I emailed Biostar to figure out if I can move them from slots a1, b1 to slots a2, b2 without having any performance issues but they haven't responded. The manual doesn't mention anything about it making a difference but I have no idea. Thanks again.

Damn, there should be at least a mm or two clearance there. It would be tight, but I would have bet a lot of money that it would fit...

Edit: Never mind, there isn't a side fan, which makes me wonder even more how a 212+/Evo won't fit.

Worse case scenario I can take a picture when I get home tonight if that will make things easier. I put an additional fan on the top of the case so yes I can take that side fan out If i need to. I don't think airflow is a problem, it's really just the heatsink.

Just go with the one WR2 suggested. You'll be good to go then and no worries with case clearance.

@ DJDeCiBeL;

I had to check several of the NZXT Source 210 case listings and found a note about the Hyper 212 in one of the Elite cases.

Yeah, I see that now, I just still don't understand it, lol. I knew it'd be tight, but I definitely didn't expect it to not fit at all.

The reviews on this heatsink look great! I'm going to order tonight if I don't see anything else here before then. Thank you guys so much, I really do appreciate it.

If you'd like more options in CPU coolers - let us know.

Last question...I noticed some people saying the fan isn't great and replaced it. Can you use any 92mm to replace it? I'm looking for quiet to be honest, any suggestions?

If you looked at the FrostyTech review you'll see that at low speed it's one of the quieter coolers.
It's only when it's spun up that it moves up the chart.

-> My suggestion is to test it out and see how it performs in your system. If it's satisfactory, well and good.

If not - stop by and we can help you find a replacement fan (Some of the NZXT fans will be good candidates).

Also, you can probably adjust the CPU fan profile with your motherboard BIOS or utility programs. It cools well enough you can adjust the fan profile lower to keep it quieter longer into a heavy workload.

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.
