Low Profile Cooling Options

post #1 of 5
Thread Starter 
Hey y'all,

I'm putting together a SFF system that will be relatively high-end and used for gaming. The case I'll be using is a Lian-Li PC-V354, which has a 125mm clearance listed for the CPU cooler. The CPU I'll be using is a Core i5 4670k that I'd like to achieve a medium OC on. With the smaller case, and limited options for coolers, I need to get the best performance possible. My current thoughts are either a Noctua NH-U9B SE2 or a Silverstone NT06-pro (with 2 fans). However, this will be my first experience OCing so I don't have much insight in regards to necessary cooling. What do y'all think of these options? Are there better ones that meet the 125mm hight requirement?

As a side note, the height clearance is a result of the psu covering the mobo. I've seen one case on another forum that fit a Megahelms rev b by rotating it sideways, but I don't know if this works with all heatsinks or if the limitations reside in mobo layout. Any information in this area would be welcome as well.

I think the C14 would be the best option personally, it has some great results. Or some sort of water cooling if you can fit something.

Noctua NH-U9B SE2 is a good choice. It will flow air thought case better than a downflow will. Problem with downflow is their heated exhaust mixes with case air raising the temp of air going into cooler and thus not cooling the CPU as well as it could. Cases with a vent above cooler fan work well if downflow fan is reversed and pulls air from cooler and it vents out the case vent above it. wink.gif

I was looking at the C14, but I'll only be able to use it with one fan, which seems like it would take away from its potential. Do you think it would still perform better than a fully optimized U9B?

As for water, I know the h50 and 60 will fit, but they have to be mounted on the bottom 120mm location. I'm using a 7990, so I don't think a push/pull configuration will fit with such a long card. Not to mention that it messes with the overall airflow of the case.

The U9B seems to be the favored cooler for people using this case. From what I've seen, it should be able to manage what I need it to, although temps may not be anything to brag about. I see what you mean about the top-down coolers. Would you mount the U9B vertically to exhaust straight out of the top fan or horizontally to fall in line with the airflow from the front fans? I will have a 120mm exhaust fan in the rear as well.

No idea which would be best but probably out the back. Wouldn't exhausting otu the side would mean pulling air from behind GPU?
