... well not quite. Seeing as I'm @ 458FSB, I had a bit of free time today and decided to crack my case open to see how my new heatsink was doing... no problems there.<br />
<br />
However, I can't touch the northbridge heatsink for longer than 1 or 2 seconds before I feel my finger burning.<br />
<br />
1- Is this a problem, or quite common?<br />
2- Look at the picture below:<br />
<br />
<img src="http://img45.imageshack.us/img45/9459/img0027ow4.jpg" border="0" alt="" onload="NcodeImageResizer.createOn(this);" /><br />
<br />
As you can see, the Arctic Cooler Freezer 7 Pro is "overlaping" the NB heatsink.... I've seen people do some mods by placing a small 40mm fan on it, but I was hoping for something a little more... long term.<br />
<br />
On the left of the picture would be my PCIe Grahpics card (not shown) and at the bottom are the RAM slots (partially shown). Bear in mind that this picture was taken @ an angle, and there isn't much more than 3cm to the left before hitting the GFX card.<br />
<br />
<br />
So, should I worry about it, or is this not the end of the world. I'm happy to buy a NB heatsink, but honestly don't feel like taking the mobo out (would I have to?, is it hard to install?)<br />
<br />
Thanks for your advice,<br />
<br />

Well If you have a temp probe you could find what the actual temp is. I believe they can get pretty hot but you should try to find the actual temp before doing anything else

If you decide to put active cooling on it this is a good one... <br />

It should give the temp in BIOS. As long as its not above 60C it should be fine.

I don't have a temp probe, and I've never seen temp information in the BIOS. Finally, as can be seen in the picture, I need a smallish NB heatsink... or maybe something like the HR-05, but placed facing the CPU cooler (as opposed to facing the back of the case).

Yeah, just slap a 40mm fan on it. Also, if you already haven't done so, yank the stock HS off the NB, clean all the gunk off and use a little AS5 and reapply the HS. Between that and a fan, you should see a big improvement.

The NB on the DS3's are known to get hot past 450 FSB.

</div>Yeah this is what I would do if I were you. Also remember that by "improvement" he means chip temp, not heatsink temp. After you change the paste the heatsink will actually get hotter but that's good because it means more of the heat is being transfered away from the chip into the heatsink.

Alright, sounds like a plan... now I have to go buy small 40 MM fan though! I have some zipties and some string, I'll see if that will help...<br />
<br />
Is it easy taking off the NB heatsink?

yup its pretty simple, see the white pins? well squeeze the bottom of them if you can and pull, they should pop right out. and to reinstall just push them back in. Simple as that.

</div>You might be able to screw the fan directly in between the heatsink fins. You won't know until you do a test placement.

I looked at my options and 40mm fans are pretty hard to come by in Canada, at least reasonably priced ones.... however, I have 2 choices:<br />
<br />
<a href="http://www.ncix.com/products/index.php?sku=18623&vpn=ZM-NBF47&manufacture=ZALMAN%20TECH" target="_blank">http://www.ncix.com/products/index.p...=ZALMAN%20TECH</a><br />
<br />
or <br />
<br />
<a href="http://www.ncix.com/products/index.php?sku=15865&vpn=40MM%20CASE%20FAN&manufacture=ANTEC" target="_blank">http://www.ncix.com/products/index.p...ufacture=ANTEC</a><br />
<br />
bear in mind that I have to pay 10 shipping no matter what I do.

You can't base something like that on touch. Your body temperature is just below 100 degrees F, which is around 37 degrees C. At this temperature, you will start to definately feel the heat (almost as hot as a typical hot tub). But, as I'm sure you are aware, 37 deg C is quite good for a northbridge temperature. In other words, just because yours is getting hot to the touch doesn't mean the temperature is outrageous and/or worrisome.

If you can put a good 120 in the front of the case and another in the back that should be fine I had a PW5D and the NB was so hot you couldent hold you finger on it as well but just added a side fan and beefed up the cross venting.
