Is Thermal Paste Nesseccary?!?!?!?!

No because all stock heatsinks come with preapplied thermal paste on the bottom,you remove the paper thing that keeps it moist and ready and then apply the heatsink onto the cpu with the thermal paste area pretty much right ontop.If you bought another cooler,you need to get thermal paste unless it already comes with it.
 
The stock will either have thermal paste or thermal pads (not sure bout c2d's), thought it's always nice to whipe those off and apply some fresh AC5.
 
Your cpu won't be ruined in only a few seconds. My last case saw the fan go on the aftermarket cooler there bringing the cpu to the max temp. That was after the system had been on for several hours. Upon installing the cpu on the present build the system was started right after apply Artic Silver 5 and the 3rd party cooler to reach the board's own max temp.

It takes more then a few seconds for any cpu to reach normal operating temps alone. But if you run one for too long without a cooling method inplace that will damage or totally ruin a cpu after it overheats.
 
well the intel e6600 comes with a "thermal pad". it's like 3 strips of thermal gunk attached to the heatsink. That's all i used. is that good enough?

Yes, that's fine. Thermal paste will keep your temperatures a bit lower, but unless you're looking for significant overclocks it's not really necessary. The Core 2 Duos run cool anyway.

OCing isn't the only thing but one big thing that will see temps rise fast. On any cpu you want adequate according to your use. If you game and OC with a stock hsf chances are that the temps will start climbing as the pad wears and hardens. If you load large programs that demand cpu time or leave your system running day and night then you have to look into better then stock.
 
Geeks.com is right about the CPU burning out in seconds. You wouldn't believe the crap people tried to pull on me and the stories I heard when people brought in dead CPUs and expected me to replace them under warranty. Yeah. Right. I told them to send them back to the manufacturer.

Anyways. If you're a purist, you can scrape off the thermal paste that's on it and put on some Arctic Silver. It isn't necessary, but some people just feel better when they do and it does drop your temps a degree or two.

Just for the record, there are no specific coolers made for core 2 duos, the c2d's use the same coolers as any other LGA775 chip. Any cooler marked as either UNIVERSAL or LGA775 will fit, ther cooling performance is up to how much you want to spend. I suggest the Arcitic Cooling Freezer 7 PRO. An extremely good cooler and in some cases beats the top line zalman coolers, which brings me to my next point. Any of the zalman super flower or zalman 100% copper ones are very good too.

For decent enough cooling you should expect to pay anywhere in the reigon of £25-£45 (GBP) Unless you want water cooling, phase change cooling or peltier cooling, then you can add a 0 to the end of both of those prices.

Actually you missed the big one ... vcore! :)

Yes but for those scenarios to actually happen you need a lot of stupidity.

This heatsink is pretty sweet :)

Others will point at a water cooling setup to see the lowest temps.

I think it's fair to assume the heatsink being referred to here is for the CPU, not as a part of a rad.
 
"Actually you missed the big one ... vcore! :)"

It depends on what you mean regarding VCore?
Putting it All Together By: Dan Mepham
So the question then becomes one of the transient state. How long does it take the voltage to reach its intended state (VCC), and how can we reduce the time needed to do so? Part of the time required depends on the design and physical properties of the materials. There’s really nothing you can do about that, although engineers spend countless hours testing different designs and materials. Fortunately, we can produce the effect of reducing the transient time by increasing the VCC (or rather increasing the difference between VSS and VCC). To illustrate, consider the image below. The red line (VCC+) indicates the new, increased voltage, while the grey VCC indicates the default (proper) voltage for the processor.

When we have VCC+ (or the intended voltage) set to a higher value, it takes less time for our voltage to reach the actual VCC needed by our logic gates. Now, if we decrease the cycle time, our logic highs still come through as logic highs, thanks to the higher core voltage.

10391.gif

Basically, the voltage produces an exponential curve. By increasing VCORE, we're causing the voltage to attempt to reach a higher value in the same amount of time. In hurrying up to the higher value, the voltage reaches our original, desired voltage slightly faster. Unfortunately, we don’t have a door example to illustrate this one, so you’ll have to take our word for it!

one extreme is with Phase Change though.

if you had a cold-bugged 939 opty (like a CAB2E) the only way to get temps-up was to put no thermal paste in, and they would still be at a nice -18 or so...

well, thats an extreme case, but its not-required as such, all though with air or basic water cooling, i would allways go for some AS5 or some SHin Etsu (it very expensive, but the best!) and probubly go for an Arctic cooling Freezer 7 Pro ( ithink thats what it called) for your HSF.

I personally sware by water-cooling, because every PC i have had has it.. it makes Air cooling seem so noisy, but i wouldn't reccomend it for a begginer, becuase well, expensive thing go wrong...!



Go for a Freezer and get some half-decent case fans, like Akasa Ambers or something....
