how much of a temp drop do you really get?

[Petebert]

I've been over clocking my cpu's for a few years now, just got my E6400 and I'm pretty impressed with the stock heatsink. The thing is huge for a stock cooler and I like the design on it. So now it seems to sell products the aftermarket has just made their heatsinks bigger but how much of a difference are you guys actually seeing? Just curious, I havent oc'd my new conroe yet but will eventually and I'm not one to spend a ton on cooling.

So I'm wondering how much of a drop are you guys getting out of the lower end heatsinks? I see the popular artic freezer 7 on newegg, I like how they spun it around so the heat goes up instead of sideways.

Is it the tube thing making a big difference now?

Is there a post anywhere showing difference from stock to different after market ones?

personally i never used the stock sink. my heatsink is a Scythe Ninja, pretty cheap nowadays. from what i've seen, the MAX you might get with a stock cooler, with acceptable temps is around 3ghz. now, with a $30 cooler like mine, you have a chance at another 500mhz...seems worth it to me. :)

well right now I dont think I even want to bump it up with the stock one since I'm at about 35c at idle according to the gigaybte software anyways. I'd like to keep that temp at idle so I want a better hsf before I bump it up.

oh and to answer one of my own questions, here's a roundup

35c idle is super low. i idle at 50ish and load around 63c. this is well within acceptable ranges IMO.

ya I dont know what these cpu's should run, havent caught up with everything new yet. My last build was a Athlon 2100, had a SLK-700 on top, as a 2700 it idled at 36 and topped at 50 or so.

ya, those temps on those CPU's were read by a little probe in the socket. so it was actually reading the ambient temps underneath the CPU AFAIK. these cpu's read the temps much differently, you are getting a reading from inside the core itself.

My p4 820 D @3.2 was 52c loaded on stock conroe HS but with the fan reversed. With the regular stock fan blowing down I was getting 58c.

Got a thermalright si-128 and now its running 45c @ 3.7 (same voltage) with the fan sucking air and blowing into a duct to prevent churning.

I would say that was a healthy drop.

The conroe stock cooler has a tremendous churn going on with almost no sides to the fan; air goes in, hot air immediately circulates back into the fan to get reheated. Pretty poor design. Also the central hub is hollow with no air flow at all!

Of course the conroe series will be substantially cooler, probably at least 10-15c cooler.
