Just put together my new system with following specs...<br />
<br />
P5B dlx<br />
E6600 (SL9S8, batch L627A906, 08/30/06)<br />
Antec Trio 550 psu<br />
<br />
What I'm finding is even with very conservative overclocking the temps seems really high. I started off with the Big Typhoon + AS5 and then switched over to Intel stock cooling just to compare. Both resulted in around same temps (~1-2 degrees). When I removed the BT, the thermal grease seemed to be perfectly spread (used recommended grain of rice method). Intel HS is now using stock thermal material.<br />
<br />
Here are some results...<br />
<br />
<u>FSB @ 300 (2.7005 cpu), mem mult 2 (600), Vcore set to AUTO</u><br />
<br />
Temps (Idle/Prime95 Load)<br />
<br />
38/57c Asus PC Probe<br />
<br />
45/63c CoreTemp<br />
<br />
mb 35c<br />
<br />
<br />
<u>Stock Speeds (266/2.4ghz)</u><br />
<br />
31/52c PC Probe<br />
<br />
36/57c CoreTemp<br />
<br />
mb 34c<br />
<br />
After a couple of hours of heavy Prime95 testing at both speeds I didn't get any errors..but the temps just seem to hot to be safe. All of these readings are with my case cover <b>off</b>. They go up about 5 degrees with it closed. Am I crazy or do these seem really hot for such moderate overclocking? I'm tempted to try another aftermarket cooler, but after such poor results with the Big Typhoon I'm skeptical. Any ideas or suggestions appreciated.<br />
<br />
Thanks,<br />

Ok, been running some more tests with P95 at higher speeds.<br><br>
Went up to 320fsb (2.88ghz) then tried 333fsb (3ghz) and noticed my temps remained at about the same level at idle and load as 300fsb (+- 1 degree). However, at 333 P95 would give me the following error on both instances after a few minutes..<br><br>
"FATAL ERROR: Rounding was 0.5, expected less than 0.4"<br><br>
I have my Vcore locked to 1.325v right now. Should I try bumping up to 1.35 and give it another go at 333fsb?<br><br>
Thanks,<br>

First, fill in your "System Specs" via the User CP at the top of the page. Knowing what you have will get you more attention. <img alt="" class="inlineimg" src="/images/smilies/smile.gif" style="border:0px solid;" title="Smile">

Ya fill in your specs at usercp button on the top of the page, makes things much easier.<br><br>
Did you really clean the surfaces well before you put the BT on? Clean off all the old paste. Then once you think it's clean, clean it <b>again</b>, and then maybe once or twice more. Then once you really know it's clean (both cpu and BT), make sure there's <b>no</b> residue or debris whatsoever, then do the BB size dab and reseat. Do this every time you switch coolers. Also, make sure you have your BT seated tight enough, nice 'n snug to the cpu, although you don't wanna go crazy and overtighten with all you're might either.<br><br><br>
Use different temp programs (Intel TAT, speefan, asus pc probe, coretemp, etc), then you need to compare you're results with what others are getting with the same cooling/cpu/mobo. Good luck with it <img alt="" class="inlineimg" src="/images/smilies/thumb.gif" style="border:0px solid;" title="Thumb"> .

The BT was the first heatsink I put on the cpu, and I did make sure everything was clean just in case. Even gave the heatsink a wipe with 91% alcohol and a coffee filter just to be safe. As I said before, when I removed the BT it looked like the AS5 had been spread pretty much perfectly...but maybe the nuts were not tight enough. Anyway, I think I'd prefer another cooling solution since the BT was way to tall for my case, putting the fan too close to the cover panel for my taste (all my heat testing was doe with the cover OFF btw).<br />
<br />
Thanks,<br />

Your specs say your using stock cooling is that right? My Big T temps under TAT at 3.6ghz *e6600 run around 60c on both cores under full load folding.<br><br>
How much AS5 did you put on? I dont use much at all in fact I use almost none <img alt="" class="inlineimg" src="/images/smilies/wink.gif" style="border:0px solid;" title="Wink"><br>
1) I spread a foggy coating over the bottom of the Big T. By foggy I do this by placing 1/8 BB sized dot and spread it until it just fogs the shine.<br>
2) I then add the usual 1/2 BB size dot dead center of the CPU heat shield.<br>
3) I alternate the screw tightening in a criscross fashion so that I am applying even pressure across the CPU.<br><br>
You probably did the same thing right? If not you might want to consider it regardless of the cooling you are using...(with the exception of phase and if you want details on that PM me <img alt="" class="inlineimg" src="/images/smilies/smile.gif" style="border:0px solid;" title="Smile">

Thanks for all the great info and advice, guys. So, any recommendations for a replacement cooler for the Big Typhoon that isnt as tall? Even something that is an inch or two shorter would work much better in my case.<br />

Why not just replace the stock 54CFM fan on the BT, for something higher?<br />
I suggest the <a href="http://www.newegg.com/Product/Product.asp?Item=N82E16811999344" target="_blank">SilverStone FM121 110CFM</a> fan. <br />
That BT and FM121 combo keeps my C2D (2.90ghz 1.34Vcore) under 47C dual Prime95 and 54C during Intel TAT 100% Load on both cores.<br />
<br />
Edit:<br />
<br />
\\/ The FM121 is the same size as stock fan....but whatever you say <img src="/images/smilies/kookoo.gif" border="0" alt="" title="Kookoo" class="inlineimg" />

Because, as I said, it's too tall. <img alt="" class="inlineimg" src="/images/smilies/biggrin.gif" style="border:0px solid;" title="Big Grin">

go with the zalman 9500 it cools just as well and blows out the back instead of sucking air in form the top. It will cool just as well with your case closed and I challenge anyone to prove me otherwise...any takers <img alt="" class="inlineimg" src="/images/smilies/wink.gif" style="border:0px solid;" title="Wink">

Yeah, I think the 9500 is the way to go for sure with my case. I know some feel it doesn't cool the NB the way some of the others do but that's not too big of a deal in my mind.<br><br>
thanks,<br>

That fatal error you got, it would seem because of low VC IMO. <br />
<br />
This here is what I use to run my system 24/7, well, except for RAM which is now at 833mhz not 999mhz: <br />
<br />
<div align="center"><a href="http://s13.photobucket.com/albums/a291/Coppi/001.jpg" target="_blank"><img src="http://s13.photobucket.com/albums/a291/Coppi/th_001.jpg" border="0" alt="" onload="NcodeImageResizer.createOn(this);" /></a>___<a href="http://s13.photobucket.com/albums/a291/Coppi/002.jpg" target="_blank"><img src="http://s13.photobucket.com/albums/a291/Coppi/th_002.jpg" border="0" alt="" onload="NcodeImageResizer.createOn(this);" /></a>___<a href="http://s13.photobucket.com/albums/a291/Coppi/003.jpg" target="_blank"><img src="http://s13.photobucket.com/albums/a291/Coppi/th_003.jpg" border="0" alt="" onload="NcodeImageResizer.createOn(this);" /></a></div><br />
And see my Vc set to AUTO? At 333fsb, my CPU uses 1.3840Vc which is more than your 1.32xxVc, so try those settings and see if it works. <br />
<br />
As for the TTBT not cooling it of properly, sounds like either the heat-spreader might be concave and therefore the HSF base might not be making a good contact. <br />
Either way, see if tightening screws of the TTBT a little more helps or I'd suggest you put a 120mm fan on the side panel directing it straight in between the video card and CPU. The heat generated by the card might be one reason why you see the higher temps, the sensor might be catching some of the heat generated by the Video card. Might be.

The size of the lower case "o" in your system specs is 1/2 BB size.

if i were u i would look at zallman's i have one on mydesktop right now and its great. they have various models but i have a copper heatsink and they are really quiet. if ur also interested about overclocking ur graphics card they have really good vga coolers too. both very quiet

Ok, I ordered an Arctic Cooling Freezer 7 Pro for $16 (what a deal) and will see how that works. I chose it over the Zalman because of the price and the fact that I won't have to take my mobo out and remove the BT backing pad to install. Will post the results.<br><br>

However, I am currently using my old 9500 on my E6700, temporarily.....I am working on water for it so no reason to buy another air cooler........at stock speeds and 1.25v I am getting 42c load temps, and the AS5 has not cured yet. My ambient in the room with the E6700 is about 22-23c.<br><br>
So I would say that there is something wrong with your BT install and or case set-up for airflow to be getting those temps.<br><br>
However, if you're buying a new cooler anyway, I would recomend the Noctua NH-U12, check my sig...... <img alt="" class="inlineimg" src="/images/smilies/wink.gif" style="border:0px solid;" title="Wink"><img alt="" class="inlineimg" src="/images/smilies/biggrin.gif" style="border:0px solid;" title="Big Grin">

</div>Well, the test I ran were with the case cover OFF, so plenty of airflow going on. I would like to think the BT was installed incorrectly somehow too, but when I removed it the AS5 seemed perfectly spread by the force of the heatsink clamp. I'm afraid what I'm looking at is a grossly concave IHS on my e6600 and will check and see when I go to install the Freezer 7 Pro. Lapping doesn't sound like my idea of fun, so hopefully I can get acceptable temps with the new cooler at 2.7ghz. Kinda makes me mad since most seem to be getting WAY better overclocks with the 6600 and even 6400.
