SG33G5: Replacing the ICE Heatsink

[Sudos]

In the while since I've last posted, I've acquired a Q6600 for my trusty SG33G5.
I've replaced the stock shuttle fan with a Scythe 92mm PWM for pull and a stock Intel old-style 92mm LGA775 heatsink fan as a push internally in the case.
I've made several wire-routing changes to get almost-optimal airflow through the case.
However, my temps suck. I'm considering doing some overclocking with the Q6600 to around the 3.2 to 3.6GHz range. My E8200 was able to handle an 800MHz overclock without any problems but thermal, when it was installed. This makes me worried that I'm going to overheat if I have this thing clocked too high, even if the overclock is stable. (note: I use AS5.)

As such, I'm looking into replacing the ICE heatsink with something else. I'm looking into purchasing a Scythe Big Shuriken SCBSK-1000, but since the ICE uses a particularly weird length between the mounting screwholes not of the LGA775 standard length, I'm not quite sure that it will fit the bill, else because of space due to the length of said heatsink. Shuttle really knows how to mess with their consumers in that one spot.

I'm looking for the temps of anyone with a similar/same case as the SG33G5 and their temps with a Q6600, and possibly the thermal compound they use. Although all of my cores are idling at stock in the high-30C range, it'd be nice to bring them lower before the overclock and not have to worry about it later. If anyone has done any heatsink modifications outside of removing the sheath and honeycomb grille in the back of the case, as far as replacing the heatsink itself, I'm completely open to suggestions.


on an off-topic note, it seems that having less than 25 posts now disabled my signature editing... I can't even change it to reflect! D:

Rather late reply here....

I would personally look at changing the fans that are with the ICE cooler and think about doing the PUSH - PULL modification to reduce the temperatures of the system.

The ICE Cooler is actually rather efficient, which is quite surprising really.

Also if you want your Signature changed then PM me and I'll make the change for you.

Currently the fans are already in a push-pull. Since my last post I replaced the Scythe with a thicker 92mm rewired Delta PWM from a Dell Precision server I had lying around.
on Ultra-Low the fan speed is the same as that of the Intel stock fan hugging the heatsink. (Because I can't post links or images, I can't show an image of how it currently looks.) I can't find my sheath, so I can't put that back in to put the Scythe PWM in the place of the Intel fan at the moment being. the Q6600 came pre-lapped from eBay courtesy of the original owner (the fact that it was lapped is why I got it in the first place!) and the contact surface of my ICE is just a smidge worn in the area around the actual contact surface... I'm considering lapping it myself and seeing how that works out. I did it successfully to the aluminum-plated heatsink in my decrepit Latitude C840 laptop, and that lowered my temperatures on that unit by a substantial amount that i8kfanGUI wasn't spinning the fans as often.

Shuttle had good intentions with the ICE heatsink, don't get me wrong, but I, myself, am not sure about the entire distilled water-filled heatpipe concept; Hence, this is why I'm looking for the widths between the screwholes and/or the Intel equivalent to such. someone mentioned it before someplace, but I haven't been able to get a straight answer, let alone any answer at all as to this. It is as if the people who are looking down upon this lowly thread know the dimensions but aren't telling in fear that one might fabricate and profit from such a thing.  

My only other question would be if there's a BIOS I should downgrade to from this one, specifically to one where only the 65nm chips were supported. I understand there's a BIOS revision with some temp readout problems... and I'm not so sure Shuttle fixed it very well, in the back of my mind. Any recommendations on this would be welcome as well.

Really, if I can't get something like this going, I might have to look into other options as far as an LGA775 board and such. This Shuttle has so far lasted me two and a half years of wonderful use, (minus the three RMA repairs in the process, expected) and if I can't get these temperatures to fall down to a more reasonable level, I might have to do just that. In the time since my posting, the temperatures have risen to the mid-40 to 50C range, with the ambient room temperature about 20-22C... the heatsink is clean of dust, there's nothing blocking the airflow (SATA cables are tucked under the heard drives, only one molex plug is being used for a Molex-SATA adapter (DVD burner) and the rest are tucked behind/under the PSU, which has also been cleaned and is running cooler than it was before.

None of it makes sense, and yet, it makes perfect sense. I'm going out of my mind.
