Do they make fanless heatsinks for 775/1366

I am wonering if they make fanless heatsinks for 775/1366? My oem cpu fan sounds like a jet engine. I found thor's hammer wich says fans are optional and for best cooling do a push pull. But are they only needed for over clocking? I have a q6600 and want to upgrade to core i7 in the future. So what do you guys say? Seen anything like that?

fans are only optional if your case has very good airflow, if the air is not moving through you case fast enough it wont move through the heatsink well enough to keep the CPU below dangerous temperatures. Passively cooled items tend to have massive heatsinks to compensate for the cooling efficiency lost from not having a fan. Your best option is to get some quite, 120mm, low RPM, high CFM fans and use them instead, it wont be dead silent but there are lots of other items in the system making noise too.

I have a haf 932 on the way(paid $120 at fry's today). I heard it had good air flow. Are there also any other quiet heatsinks you would suggest?

I too came up with a lot of results but I was hopping for an expert to weigh in with some food for thought.

Ensure that your case has plenty of airflow to compensate for the lack of a fan on your CPU. Get once large enough to where you reduce the risk, but take the size of your case in to consideration.

Right hand column list the quietest ones that they have tested, you could also use one of the higher performance ones that doesnt come with a fan as your case will provide sufficient airflow, but even a low speed fan will provide you significantly better cooling with a minimal noise increase but its your call.

What would be nice is a fan controller for say a 5.25 drive bay that has selectable channels for fan and temperature sensors. So you could say "if my cpu gets x degrees power fan 4 and 6 at y speed (or automatic)". That way the fans only turn on as needed like a car radiator fan. That would be the best of silent and performance computing. Plus it would be nice if it would control all the case flow operations and have profiles based on your preferred method of operation during certain tasks and conditions....... Maybe I should invent it!

Well I'm gonna call it a night for now I'll see yall' tomorrow.

I would be careful with fanless heatsinks and other coolers such as the corsair h50 on as some i7 motherboards as the IOH cooler requires the air flow from the cpu fan.
Not sure if this problem is only related to MSI x58 boards http://forum-en.msi.com/index.php?topic=133034.0

You could try a Scythe Orochi or a Scythe Zipang, but they are large.

That was something I hadn't considered my northbrige cooler is half adjacent to my heatsink so it probably dose need passive cooling. Do you guys think upgrading the fan would reduce noise significantly or do you think most of the noise comes from the air hitting the fins on the heatsink?

btw. I'll be using this board. http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01...

If its the stock fan most of the noise is coming from the fan, they dont use high quality fans on stock heatsinks because most people will never notice.

I don't know what you are using for a board but hunter gave you the best advice in that the answer lies in using 120mm fans.

Simply read the specifications for any fan you are considering and see what the noise level is when it's on full.

The one in the following link for example moves 58CFM of air and going full speed won't exceed 25.5db which is very quiet and likely not any more noticeable than your PSU fan. http://www.ncix.com/products/index.php?sku=34071

In so far as the fan control feature you mention you should check into what features your board has built into it because mine for example already allow you to make adjustments in the BIOS for fan speeds for various items so there'd really be no need to spend money on an extra item.
