Noctua NH-L9i-17xx

Very quiet replacement. Used it in an Alien x51 1st generation pc - perfect fit.

This is a beautiful little cooler, usual Noctua quality and super easy to install + silent while running.This is cooling my HTPC's i3 4130 in a Silverstone ML03 case. temp range from 30-35c doing everything I ask of it.

The build quality is top notch which makes it worth the price as installation is simple - Keeping my i3 below 60 degrees at load and 34 degrees idle despite being a tiny case with restricted airflow. Most importantly for an HTPC in the lounge it really is completely silent! At 500-1200 rpm it remains inaudible. Never had to go above this during use yet when testing it was still "quiet" even at full tilt.The included generous tube of thermal paste, Y splitter, low noise adaptor, screws and rubber mounts are all a nice touch making it much better value than "just a cooler".Amazing for only 37mm tall! Nothing else compares at this size.

Bought two of these today from Overclockers. Went and collected direct from their premises, extremely helpful staff member behind the counter. Easy to fit as the cases are HAF912 so have the hole to allow access to rear of motherboard. Cannot believe how quiet the PC now is. Running the two PC's together, you can hear how loud the old Intel stock fan really is. Checking on temperatures, it has lowered the mobo temp. by 1 degree. But the cpu and gpu run anywhere from 4-5 degree's cooler at idle. Also the fan runs 300 rpm slower. I have not fitted the low noise adaptor as it does not need it. Would recommend this cooler to anyone.

Beautifully finished. Easy to fit, compact and silent.If your short of space get one of these!
