Suggestions since I cant install a different heatsink on my hp motherboard

After doing my research I finally decided to upgrade my good ol i3 2120 with an i5 2500 (non K). Im using an old hp mptherboard with very limited upgrade paths, so it was either an i5 2500 or an i7 2600. After asking here which one would bottleneck a new gtx 970 (Im currently using a 7870 XT), people told me that an stock i5 2500 will do the job.
I bought one on ebay, got it shipped 2 days ago, and decided to install it today. I thought it was an easy process where I just had to pop out the old one, put the new one on, apply some TIM, insert the new heatsink, put everythink back as how it was, and BOOM that was it. Well, I got stuck in the part of putting the stock heatsink that came with the i5 2500. It was one with pushpins and not screws (like the one I have right now). I tried many ways to insert it, but I couldnt. I then realized that the backplate that came with the hp motherboard was blocking the screw holes in order for the new heatsink to fit through it. The backplate is not attached to the mobo with any bolts or screws, but with either some kind of adhesive, or soldered (very unlikely). I read that using a heatsink designed for an i3 wouldnt work as intended on an i5 because it wouldnt dissipate heat as efficiently as if one was using the designed coolers for it. That was the reason why I bought the i5 2500 with the original heatsink that comes with it. Anyways, I then went to a pc store (Frys) and bought a cooler master hyper 212 evo and hoped that would solve my problem. Well, it didnt. I need to use the 212 backplate in order to assemble the heatsink properly, and the only way to do that was to remove the original backplate that is attached to the hp mobo. I read that one has to be very careful when doing this process since you can easily break your mobo. One way to do it is to use a hair dryer and carefully apply heat to the attached surfaces. Now, I could try to do this but it looks like its already makeing this process into a lot of work, PLUS if for a reason or another I want to put the original backplate back, I couldnt since I already dried out the adhesive it was using, and I would have to figure out how to do that. Trying to put the 212 backplate on top of the old one is not possible because the mounts that need to be put on the top of the mobo wont fit through the holes (too tight).
So, I was thinking I may have two possible solutions here but I wasnt sure:
1. Just install the i5 2500 cpu with the original heatsink, check the temps, and if I see they are getting hotter than how they were with my i3 2120 (which probably would happen), will it be possible to add a second or more fans to my case in order to get rid of the extra heat generated? I dont know if this is viable, and how efficient it will be. Maybe I would have to get faster rpm fans than the stock haf 912s that came with it?
2. Try to find a better heatsink that fits on my motherboard without the need to detach its backplate (which I wont do because its too much work for me).

Of course you can always say: "just buy a new motherboard, you can go here and it will be this price, bla, bla, bla ..." . The thing is that Im just trying to save a few bucks and getting the max out of the current system I own. A new mobo will mean a new windows license and new compatible RAM, and of course a $200+ processor, and those are $450ish I cant afford to spend right now.

Im pretty sure an i5 2500 (3.7ghz), 2x4GB ddr3 1333 ram, msi 970, 250gb SSD, 650 bronze rated psu, win 7 64 is still a great system that would give double performance than a ps4 or xbox one (current just released titles at high or maxed with 60fps at 1080p).

EDIT: I forgot to tell you which motherboard I use:

The model of my hp oem heatsink is: hp 644724-001 and it looks like this:

Sorry for that. I just edited my first post and put some links at the end of the wall of text. There's my mobo, and the heatsink.

Sorry for the double post.

I heard also I can try and remove the pushpins from the i5 cpu and replace them with screws. I still dont know if those screws will fit perfectly through the backplate of the hp mobo though.

Since I was solo during this quest of mine, I decided to just use the same heatsink I was using with the i3. I realized its not the same one that comes with a stick i3 from intel. Its actually thicker and supposedly works good on i5s as well.

My temps at 60ish loads are around the same: ~60c.
