To clean CPU HSF or not to (not buying thermal paste)

post #1 of 17
Thread Starter 
I have an almost 3 year old CPU with its Heat Sink and Fan and never really cleaned it well.

I am getting a somewhat high temp for CPU loads (75+ Celcius)

If I am not gonna reapply any thermal paste, would it be better to just leave my CPU and HSF alone as to not "disturb" the almost 3 year old thermal paste..

Or it would be better for me to Clean the HSF thoroughly but might remove the old thermal paste?

-super duper noob.

So what's better between the two? (please don't suggest purchase of thermal paste not unless they're really cheap like 5 bucks xD)

you need to reapply thermal paste as taking the HSF off introduces air pockets into the TP

A tube of Shin Etsu is ~$6 with shipping from newegg and is far better than AS5. Buying Thermal paste is something you will not regret as it is crazy helpful and lasts for ever.

If you dont want to buy new paste, all you can do is blow air onto the HSF to clean dust away.

Definitely DO NOT clean off old thermal paste if you do not have new to apply.

Now cleaning off your old and applying new is recommended. Keep it all locked down to prevent air pockets until you get new paste.

Thermal paste is pretty cheap , cheaper than a new CPU. 75c is pretty high, if it was me, I´d take it off clean and re-seat it.
Which cooler is it, and what´s your case flow like ?

Thermal paste is much cheaper than a new CPU. Even some cheap $1 generic stuff from a local store would be better than nothing.

+rep to all the replies.

Thanks for the suggestions!

Good thing I didn't jump the gun and cleaned it (remove, clean, put back w/o new thermal P)

I have a stock cooler. IDK about Airflow but I have a fully functioning Antec 900 Case with all of its default fans (2 front, 1 back, 1 huge fan at top).

The thermal paste is there for a reason. Get some.

That's a really sweet price!

Any other recommendations? How about that Arctic Silver AA for 5 bucks?

I really don't know anything about thermal pastes and would appreciate more info from here xD

Shin Etsu is one of the best on the market, for that price you can´t go wrong.
Your case is fine as far as airflow goes. Stock coolers are generally crap and noisy, I´d definitely look at aftermarket cooling at some point.
