Cooling for Customized requirement

[enggricha]

This requirement is not for a computer as it is, but I am posting this here because I figured the best solution for my requirement is a computer component.

I need a a heat sinking solution for a customized electronic circuit that I am building, and searches all over have lead me to believe using CPU coolers are the best bet for my requirement.

So here is the question...which moderate CPU cooler has a biggest contact surface to the CPU? I hope i have made myself understandable.

I need something that is approx 60USD or Rs.4000(INR).

I would think they're all very similar. Since they all completely cover the heat spreader of any CPU, it's a performance disadvantage to make the surface area much larger than necessary.

i havent seen many different CPUs ...i was just thinking along the lines that the CPU top on some might be bigger than others?

CPU sockets haven't really changed all that much. Since the contact area on pretty much AMD or Intel is about the same its all about the mounts. Maybe just maybe in the Thunderbird/Palomino/Barton/Coppermine days they were a little smaller due to the direct contact with the die, but even then it's mostly the same size as the bottom of the heatsink usually matched up with the socket, which again really hasn't grown just increased pin density.

largest surface area blocks are NOT cpu blocks.

they are HDD blocks.

Koolance makes one:

and so does Bitspower:

If your specifically looking for a cpu block... what is the wattage of the IC your trying to cool?
CPU blocks are mostly for high wattage, like in the 300+ range.. if ur less then that, you maybe able to get away with a GPU block, or better yet, find a discontinued gpu block... sand the entire thing flat, and use that, as old left over gpu blocks can be bought at a heavy discount.

At < $60, I would assume we're talking air cooled.

There are many large passive heat sinks available from many vendors. Is the OP looking for some gigantic 1+ lb CPU cooling monstrosity, complete with multiple heat pipes and 120mm or 140mm fan, for his application?

I think you have that backwards. CPU's have up until recently floated around 100-140w. GPU's tend to be 200W+ on the mid to high end (with the ~$450-600 cards being about 300w).

we are talking about the actual block capacity.. not the TDP Chip value.. or the heat load on the actual chip.. lol...

cpu blocks are designed with better channels to handle ~3x if not more real heat value of the said chip.
This is mostly due to the area of turbulence being localized, and increasing the efficiency at which the channels can transfer heat.

This is why 95% of cpu blocks can even handle a ~400W tec, and still keep it in check.
Where as GPU, you have the cooling channels spreaded out to VRMS and other RAM.... its not a centralized cooling area on GPU blocks, even on the direct core as it would make the gpu block way too restrictive.

thanks that is the confirmation I needed... i'll look at what other options I have with this then.

Yes air cooled...no cooling monstrosity

What exactly are you looking for, then? What is it about CPU coolers that you think is applicable to your application? You can strap a fan to just about any big heatsink.

I'd think the main limitation - though -- is the areal size of the item, -- IHS, "component for an electronics project," whatever. With CPUs and CPU coolers, they're shrinking the die and reducing thermal wattage, but the die-size and IHS limit the cooling capability of any cooler, whatever the size of the base, water, air, what have you.

I might wonder if TEC coolers can offer any promise with this, now that the processor thermal wattages are back in the range that make TEC feasible.

I've been a fan of dynatron's socket f coolers since they're on sale often, mostly copper and easily mounted.

Do you have a link you can post describing and depicting these socket f coolers?

ADDENDUM:

Are you talking about something like the A2CG cooler? A picture doesn't reveal much, but there is an aluminum-colored metal square that could cover something like radiator tubes and fins ranging to some . . . mysterious TEC device . . .

last purchase was dynatron a30g:

http://www.ncix.com/detail/dynatron-a30g-amd-dual-core-cu-e0-24839-1456.htm

not a huge fan of mounting large amounts of copper through only two points, but it seemed like less work than finding a premade extruded aluminum sink and designing around that.

Ended up using a Deepcool Neptwin Cooler, because that was available to me easily. Thanks all for the details.
