Question 1

I'm looking at the pics and do not see for sure how this fits on my 4770/1150 setup. Is there a back plate not shown? - or do the nuts/washers come off and mount on the backside of the mobo? thanks for any help

Accepted Answer

This unit has an elegant and clean mounting system, it is easy to install, runs very quietly, and keeps my Intel Core i7-4771 Haswell CPU nice and cool.

The fan comes with self-adhering steel mounting plates that fit cleanly on the back of the mother board.  No instructions are included and the correct orientation of the plates is not immediately self-evident.  So one should pause and think for a moment and make sure one has the geometry correct before attaching the plates to the motherboard.  The heat exchanger block contains thermal compound printed on it.  For good measure, I added a small bead of Arctic Silver thermal paste and this seemed to work well.  Before screwing the heat exchanger in place, the fan must be snapped off to provide access to the screws.  Once the heat exchanger is mounted, the fan can be snapped back on again.  The mounting screws are held in place by small springs that facilitate installation and screw tightening.  I tightened the four screws in sequence, ½ turn at a time to achieve even pressure application against the processor.  Very simple and elegant.  I rated this unit 5 eggs.

My build components are as follows:  Antec Gaming Series One black steel case, GIGABYTE GA-Z87X-UD3H motherboard, Intel Core i7-4771 Haswell 3.5GHz LGA 1150 processor, Dynatron K17  92mm CPU cooler, Microsoft Windows 7 Professional SP1 64-bit, COUGAR  A760  model CGR B3-760 760W power supply, CORSAIR Vengeance 16GB (2 x 8GB) 240-Pin DDR3 memory, LG Black Blu-ray Burner model WH14NS40, LG Black Blu-ray ROM  model UH12NS30,  AFT PRO-57U USB 3.0 ports and card reader, ASUS Xonar Essence ST PCI Audio Card, Crucial M500 240GB SATA 2.5" 7mm SSD, Western Digital WD Black WD1002FAEX 1TB HDD,  Western Digital WD Black WD2002FAEX 2TB HDD, StarTech 1 Port PCIe IDE Controller card (for old recycled IDE hard drives), StarTech PEX1394B3LP PCIe IEEE1394 card, U.S. Robotics USR5638 V.92 PCIe Fax modem.

Question 2

To install this, I just screw in the spring loaded screws? or is there a backplate that requires me to remove the motherboard to install to this correctly?
I would prefer if this only needs to be screwed in from the top of the motherboard.

Accepted Answer

It requires a back plate (included). You are probably replacing the cooler that came with the processor that has the expanding plastic pins. This cooler is quieter and more efficient.

Question 3

Is this fan capable of cooling an i5 2500k even when OCed?

Accepted Answer

We have this unit running on an i7-4770k @ 3.50GHz. The processor temps read consistently around 70F. Hope this helps.

Question 4

What way did you mount this to your motherboard? I have tried it blowing up, blowing down, and now blowing towards the back and still running hot?

Accepted Answer

I have always mounted the CPU fan to blow towards the nearest case exhaust fan, which is usually at the rear behind the CPU socket.  Running hot in any direction probably means that the thermal paste was not used at all or not spread properly (too thick or patchy).  I usually use a business card to spread a thin, even coat on the CPU surface before mounting the heat sink.

Question 5

Can i attach a different 92mm fan instead?

Accepted Answer

You could if the fan was the same round with ears configuration.  A square fan may interfere with the spring screws for the heat sink below the body.  Plus you would have to mount the fan after installing the cooler because the screws would be inaccessible with fan installed first.  I have one on a 4.0 GHz i7 Skylake that runs completely silent, so why change it?  It is only audible during a pressure test like running 5 antivirus utilities at the same time.  Cheers!

Question 6

HOW TO  INSTALL?

Accepted Answer

Two brackets with threaded stand-offs go on the underside of the mother board. They have adhesive so stick in place. I had to play with the orientation but they do fit without interfering with the board traces.

From the top-side, the fan then screws into those stand-offs.

The fan comes loose so you can take it off if needed to get to the screws easier. After installing the heat-sink, snap the fan in-place. Take a look at the picture for the proper orientation of the fan if you forget: plastic lip goes on the sides.

Question 7

What is the noise level range of this cooler?

Accepted Answer

The noise level range of this cooler is from 17.0 dBA to 31.92 dBA, depending on the fan speed.

Question 8

What is the airflow specification of this cooler?

Accepted Answer

The airflow specification of this cooler is 17.34 CFM at 20%, 31.21 CFM at 50%, and 43.36 CFM at 100%.

Question 9

Is this cooler compatible with all Intel LGA sockets mentioned in the description?

Accepted Answer

Yes, this cooler is compatible with Intel LGA 1156, 1155, and 1151 sockets.

Question 10

Is the mounting of the fan to the heatsink horizontal?

Accepted Answer

Yes, the mounting of the fan to the heatsink is horizontal.
