Urgent help on Intel cpu cooler

Hi,
I just installed a Lga 1155 pentium g2020. While installing the cpu cooler, I thought that I Installed it wrong and removed it to check and install it again properly. While I removed it, the thermal paste was already on cpu. I have heard that if a cooler is removed /reused, then the thermal paste needs to be applied again. Is this true? Will I have to reapply thermal paste, for the cpu and it's cooler to work properly? (sorry if this is silly because I'm kind of new)

Best solution

If the computer has not been run with the cooler on, there should be little impact (although some air gaps will be formed). If the computer has been run to the point where the thermal compound has flowed and no longer matches the factory print then I will suggest replacing the thermal compound

I'm just building it now and the computer has not been run. So is it safe to run the pc?

You heard right! If the heatsink is removed for any reason then all traces of old thermal compound needs to be cleaned away using 70% (or higher) Isopropyl alcohol (rubbing alcohol) available at Walmart and other stores.

After that you can re-install the CPU/heatsink using new thermal compound such as Arctic Silver 5 per manufacturer's recommendations. Use a very thin even layer.

Re-do the CPU/heatsink installation.

@ubrales,it is really that important? I'm asking this because I'm new to this and do not have a proper idea to do all the things you mentioned, properly.
Will the cpu get damaged, if I run the pc as it is?

I disagree, I would use it and here's why I say that. If you really examine the thermal compound that's printed on the cooler, you can't help but note that it is not smooth and there is no physical way to place it on without air bubbles forming (and nowhere are there directions to smooth it before placing it on the CPU). Any substantial traces of air should be displaced by the compression and heating of the thermal compound, not by the act of mating the cooler to the CPU.
Granted, changing the thermal compound would not be in any way a bad idea but I'm not seeing it as a necessity.

Yes it is very important and I shall explain why.

Any time the heatsink is dismantled from the CPU, the thermal compound does not separate in an even manner. When microscopically viewed the thermal compound will appear in very uneven globs; some on the CPU heat spreader, and some on the heatsink base.

Trying to smooth-out this compound will not result in an even and very thin layer. This is why it is better to clean off all traces of the existing compound and start out with a fresh application. In other words, re-do the process.

Fried man, you gave a type of relief to me, as I honestly do not want to do all those things myself. Soo, what should I do remains the big question. I'm not worried about temps, as it is just a plain web surfing build with a pentium and without a dedicated gpu. Just that the temps should not be something like 60-80,when I finish building the pc and use it.

@ubrales,i had not messed with the thermal paste and the time I removed it, I saw it evenly spread on cpu, but not that evenly spread on the cpu cooler.

Cleaning and re-doing will take a few minutes, and it is a one-time task.The benefits of doing it right far outweigh the risks of taking short-cuts.

But the problem is that I currently do not have thermal paste. And even if I get it, I will be doing it for the first time.

Try it and monitor your temps - I wouldn't expect to see above 50C. If your temps are higher than that, I would say then replace thermal compound
You can use SpeedFan or CoreTemp or... to monitor temps

I strongly believe in doing things right the first time. Get some Arctic Sliver 5 thermal compound. http://www.arcticsilver.com/# - application procedure explained here.

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

There are several good videos on YouTube that will explain the application procedure.

I am just 50/50 now and don't know what to do. Maybe, I will try using it first and then see. Ubrales, I know that it is always good to do things right in the first place but I'm not from the US and that Newegg website is Useless for me to purchase things here. Getting thermal paste and all will be a mess here(at least for me due to myself being from a small town.)
Sorry but I'm still confused. :(

The Newegg site is for reference. Use that information to procure the items you need. In which country are you located in?

I have one more question. There is a 4pin 12v connector on motherboard but my power supply only has a 6pin and a 8pin. Both of them fit in the 4pin connector with the remaining part of the pin left out. Is this OK?

The 4-pins connector comes either as a dedicated 4-pin or as an 8-pins connector that splits into 2. Use either of the 2 halves.

I am in Chicago and I have extensively traveled in the US, some parts of the EU, and India. Yes I have been to Aurangabad, Mumbai, and Pune in Maharashtra (sight-seeing).

OK, I connected all things without changing thermal paste and the cpu is idling at 34 degree's. Is this idle temp OK for a pentium?

Yes it looks ok to me. What program did you use to check the temps? RealTemp?

As it is a new pc, there is no os and the temps are from bios.

Looks fine. Since you picked Friedman's suggestion, I am selecting his answer as the best answer.

Good luck!

I will think a bit before I select a best answer.
Anyways, installing Windows 7 and it's like a rocket. I have a 64 gb ssd and no hdd. Yes, you heard it right - there is no hdd In the computer, only an 64gb ssd as it is a totally Internet surfing build and I only need to install os on hdd.

Sorry, but last question, I have 2gig ram, should I install 32bit windows or 64 but windows? I may upgrade it to 4gig in future.

I did not know that people other than op can select best answer! Anyways, it was also fair to select fried man's answer as best

I'll recommend installing the 64bit version of Windows. The only really good reason IMO to use the 32bit version is if you have programs that require 32bit and cannot run in the 64bit environment. The 32 bit version also has a limit of 3.5GB usable ram. With 64bit, 2GB is the minimum amount of ram suggested so, depending upon the programs you have running at any given time, you could run into issues with the computer stuttering, hanging or otherwise acting "ram starved" but you should have no issues adding or upgrading ram (if needed)

Thanks for the reply friedman. I installed the 64bit version and upgraded the RAM to add 2 more gigs.So 4 GB now.
I saw in task manager that the 2 GB RAM got filled up when opening around 6 tabs in google chrome and the page file was being used. So decided to upgrade to 4gb.
4 GB seems to be the minimum nowadays for optimal performance.
Anyways,the computer is running fine and your suggestion fully worked without giving any problems.Thank you very much!
