Horrible start to my PC upgrade..

Managed to gut the beast. Removed all cables from all hardware that are linked to the faulty PSU. Taken out the Motherboard, GPU, RAM and the network card.

Removed the old HSF and removed the old compound from the CPU and then the CPU followed by unboxing the R1.

I then add the new base plate and bracket for the R1 and proceed to re place the CPU.

CPU pins bent in the process of removal and had to carefully bend back into correct angles.

Could not manage to place the CPU back into to socket and couldn't figure out the issue for about 1 hour max. After that time i put a small amount of pressure on the CPU and it pushed into place. I felt stupid..

I start adding the compound.
Stressed and tired, used up a bunch of the new compound horribly and it left me with a tiny amount to (hopefully) equalise the distribution of heat.

Installed the R1 with great difficulty. Screws would not line up correctly after a multitude of attempts. Roughly 2 hours pass was completely exhausted and refused to give up but I finally did.

My question is I fell like I should by some new compound and wipes and start again. There is not a great amount of compound on the CPU and HSF and im worried if I actually dont have a sufficient amount of Compound. It was like a droplet then what ever I could scrap up from the card I used.

Arrgh.. I feel so stupid... There is a lesson I have learnt. Never do things when you are utterly exhausted.

Also, you don't need a lot of thermal compound. A little will go a long way. Also, you should NEVER reuse the compound from a previous use.

If you have a thin film covering your CPU after applying pressure with your heatsink, then you likely have enough. All you are trying to do is fill the minuscule variations in the CPU and HSF surfaces. Like I said, not a lot is needed.

Regarding the CPU insertion, since you had previously bent some pins, it may not seat as easily as if the pins were perfectly straight. I, too, recommend that you inspect the CPU for any possible damage. Of course, that means new thermal compound.

Up to you. Good luck.

Oh geez thats a worry :/

Alright I will do that. I will get some more compunc while im at it.

Also ove looked online at a lot of forums and people say that if the pims are bent its possible that the CPU will still work they can just softly be bent back into place. I am unsure if this is correct or not as there are a lot of trolls on the internet obviously haha

^^^^^^^^

a grain of rice sized drop of thermal paste is all you need for reference.

if you bent a cpu pin, a very fine sewing pin or needle are usually the best way to fix it. the eye of a very small sewing needle is also a useful tool for fixing them.

magnifying glass helps too, so you can see them clearly.

be patient take your time, don't try to rush it the pins are quite delicate compared to the leverage a human hand can put on them.

do not try to bend the pin if its very cold in your house or if they seem overly stiff, or make any kind of "crackling" when you bend them.

if necessary turn your oven on to around 100f-150f and put the cpu on a clean metal sheet in there for around 5-10 min, not long just enough to warm it up a bit. could do it over a toaster too but be careful, don't burn yourself or drop the cpu.

you don't want it too hot to touch just kinda warmed up so the pins are easier to bend.

So I have just purchased some Arctic Silver Ceramique 2. Hope this is alright. Its a shame I wont have the Compound supplied with the R1 though.

I was at the nearest Tech shop and they said you don't need to clean the CPU with any substance and you can just wipe of the paste with a piece of soft cardboard. I might just do this...

Also I struggled to remove the CPU from the old heatseak the other day, hopefully I dont get the same issue... I had to use light heat to slowly melt the compound even though I really shouldn't have.

Oh awesome. I also read online people use a slightly warm hairdryer for 2 seconds without over heating it. Haha not sure if it was a troll. Im sure it was.

Alright I will see to it tonight and upload pictures of the CPU and HSF, THermal application etc. Hopefully it works as its a $400 or so CPU :/

Alrighty! All is well. :wahoo:

I removed the HSF from the mainboard and removed the CPU to check if there were any damaged pins

No damaged pins: http://imgur.com/62DAiC0
Unclean CPU slot: http://imgur.com/2MZ5cyc

Once I did that I completely cleaned the CPU, HSF and the CPU slot and its surrounds. I then applied some more thermal paste and double check my progress added a small fraction more as it seemed a little to less and reattached the HSF.

CPU fits correctly: http://imgur.com/dOUOFs6

HSF: http://i.imgur.com/M7hrBfF.jpg

And after a successful put together, it is all up and working again!

Final product: http://imgur.com/9rgfFEJ

Thanks again!

I honestly don't know what happened to me yesterday night.. I think I just lost my complete concentration. Tonight was by far a better outcome.
