question regarding cpu HSF compatability and possible problem

Since the specs say that the TX3 is compatible with LGA775, I would not worry any further.

If your case offers at least 140mm of clearance from motherboard to side-panel, you are golden. You may want to check your case documentation on this.

As to the fan fitments. Those are just plastic clips that you screw the fans onto and then clip onto the HSF. They are easily removable if you do not want a push-pull setup. Also you can orient the HSF in any direction to prevent RAM clearance issues.

If my Hyper 212 EVO was anything to go by, the TX3 should be completely worth the money, assuming you are not going to overclock the life out of your CPU.

i would never overclock it, i want it to last as long as it can since im poor and cant yet afford to my my 1st 100% custom pc, i was so afraid that those plastic clips where something that where stuck there for good, so glad they can be removed...speaking of which how do i do that? do i need to remove the motherboard to?, and regarding space ill show you the current fan, based off the tube thing around the fan and how wide it is i think im good, and there is a point in the case in the back with tons of holes like the side pannel so i can have the fan facing that way instead of forwards, ill show in a pic bellow, and yes i know wire hell...i had warranty to cover a new power supply which is slightly higher than the one it had before (cant remember the watts of the last one but this one is 500w and has a lot of wires

as you can see there is this huge tunnel tube thing over the fan, i think it will fit fine. that does

edit: there is like 7 inches or at least 6"4-5 inches in there...yea the case is 7 inches in depth measured from the outside 14"5 inches long and 15 inches tall

You can actually get the stock Intel HSF for the LGA775 socket here:

Amazon.com: Intel Original Socket 775 CPU Fan/Heatsink with Copper Core Center: Computers & Accessories

Based on the picture I think you should have no problems.

The clips fixing the fans to the TX3 can be removed by applying gentle pressure with your fingers or a flathead screwdriver.

Just remove the original cooler, mount the fans and retention clips on the TX3 and attach to the original Intel retention mechanism.

A good guide and review is shown here:
Cooler Master Hyper TX3 CPU Cooler Review | Hardware Secrets

YOu do not need to remove the motherboard.

The TX3 will clip on to the original Intel socket retention mechanism.

You just need to remove the original HSF by turning the retention clips and then mount the TX3 as shown in the 2nd link above.

You can mount 1 or even 2 fans, they should not interfere with the cabling (which I guess you could try to clean up some )

so i do have to remove those plastic things the current cooler is screwed into, i also dont know where to put all that cabling, there is so much of it from that power supply alone, most of it is sitting on or just above my ram =/

but to get this straight i have to have the fan pointing towards the front or above the ram so the side without a fan points towards the back where those holes are?

also, my god the 3-4 pin plug bit on this stock fan is fighting hard and will not let go, so much effort to only get it a little up

If I remember right all you have to do to remove the original HSF is turn the retention clips 90 degrees (I forget which direction) and it will unclip.

Then all you do is place the prepped TX3 with its fan on the CPU and turn/twist its own retention clips so it locks into the CPU socket's built-in retention mechanism.

Remember you need to clean off the old thermal paste from the CPU heat spreader and apply fresh thermal paste before you fit the TX3.

You can have the fan either pushing or pulling through the heatsink, so you can have it on the side facing the area with the ventilation holes and pulling air through the heatsink.

If space permits you can even have 2 fans in push-pull (you will have to buy an extra 92mm fan to do this). The TX3 comes with clips for 2 fans.

The heatsink attaches to the retention mechanism via expanding plugs. When you turn the plastic head at the top of the post, the plug expands in the socket to hold the heatsink in place.

There should be a couple of videos on Youtube.
