No. It should have silver or a ceramic base. Those compounds transfer heat much better.
Are you speaking of CPU or your GPU? It looks like both from your posts?
As sygnus21 states, brands are up to debate, but I think everyone would agree on the compound type. There is a specialised cleaner for used thermal paste as well and a primer to use after cleaning. I use both if I need to remove the cooler from the CPU. You might look and see if the FAN is removeable from the cooler to leave it intact in the future. Be less hassle.

We would..... but I get the feeling the OP wants to go the cheap easy route.

And honestly any compound would do but yeah, one of the more recognizable brands containing silver or ceramic would be best. This we agree

okay im new to applying thermal pastes so i just put it and should i let it try first before running my pc or i can run my pc immedietly ?

i can buy any thermal paste my budget for it is $60 id go buy in computer stores later for now ill have silicon based thermal pasted and would find things to remove those i applied

can you mention the names of those things your saying in removing cooling and after cleaning etc? so i can buy them

Put a little dab on the processor and install the heatsink. That's it. But before doing anything please look through the links I posted for you here - https://www.sevenforums.com/general-d...ml#post1345894

ive bought a new thermal paste and applied it using the guide but still speedfan reads at 70-80C" T_T

EDIT: i've removed it again and put another thermal paste

so far this is my idle temp 43C"
loaded with 4 wonderland online 55-65C"

IntelBurinTest V2.50 temps at 81C"
is this normal now?

someone suggested me too that every 5-6 months i shall remove the thermal paste again and replace it with a new one ?

Ceramic is best because it can withstand high temps without changing its properties. Think of the ceramic tile on the shuttle.

There's really no need to do that unless you're doing extreme overclocking where the heat can break down the paste - highly unlikely you'll fall in that category.
Bottom line is "every 5-6 months" completely unnecessary as the paste will certainly last a lot longer than that.

The only time I "replace" my paste is if I swap CPU's or remove the heatsink for some reason. Iíve had systems run for years without replacing the thermo paste under normal use.

My two cents.

That's correct no need to replace thermal paste unless you do a CPU swap or get a new cooler. One more thing, after you apply the paste and place the cooler on it you're done, clamp it down. do not remove it to see how the paste spread. the on/off cycles will cure it and the tension on the cooler will complete the spreading process.

EDIT: I have a 6 year old PC which has been running just fine on the original factory thermal goo.

Intel Burn Test is a very very severe test, moreso than Prime 95. I'd say that number is not extreme, considering your idle temp is 43.

In a 23 C temp room, a cool running PC will probably idle in the mid 30s. If the room temp moves up 5 degrees, the idle temp will probably rise the same amount or close to it. Your idle temp may be a little high due to several factors: room temp, cramped case, not much help from case fans, etc. But I wouldn't worry about 43 degrees on a Core 2 Duo.

Arctic Silver says that on a Core 2 Duo, you should apply a thin strip of thermal paste down the center of the CPU backplate---about the thickness of uncooked spaghetti. You don't have to spread it around--the tension from the heatsink will spread it out.

Since I couldn't get specs on the AMD Turion in terms of cache, etc. (the Intel one in the title is 2M Cache, 2.20 GHz, 800 MHz FSB) I couldn't figure out which is the better processor. Does anyone know? Is there also a website I can reference that can compare them?
