Is good to sell that heatsink for some bucks that can help get a better heatsink. Is useful for FM2 chips.

It's not worth my time to try and sell it on eBay or deal with setting up a time to have some random dude show up at my house for the $10 I'd get for it. Throw it in the box and put it back with the processor if and when I sell the system.

You're just mad because you're so easy to pick on. Stop being an easy target, and suddenly people won't bother you anymore.

When you start having views that don't incite mockery, suddenly you won't be everyone's favorite punching bag around here. You'll get there, in time, but so long as you are not figuring things out independently, and instead rely on people to correct you, to try to get you to see the light... you're going to have a hard time. Do us both a favor -- if you are in fact interested in hardware, as you seem to be, then go learn about it first hand. If you're not interested, quit wasting your and everyone else's time here and bug off.

There's actually a lot of truth in what frozen said, though. You don't improve upon things arbitrarily, especially in business, but even elsewhere in the world. People that weren't trying to bust your balls picked up on that too.

So why did AMD invest money into a new cooler? Well, the answer is that they did it to improve their competitive standing with Intel. Intel can get away with simplistic, cheap coolers. AMD, however, has to fight with everything they've got. Thermal management is a huge part of the overall computer picture -- your power consumption, temperature, performance, acoustics, cost -- are dictated by it.

So let's do some fun calculus. The effect thermal performance on demand is logarithmic -- there is a point where having a better cooler will net you next to nothing in terms of creating a product that is more demanded. Performance is either linear with demand, or somewhat exponential (higher performance can create new markets). Cost follows a bell curve -- you get exponentially higher demand to a point, even with increasing costs (because those higher prices are buying you something desirable), but after a certain point, eventually too high of a cost kills your demand.

Something must have shifted, such that it is now suddenly worth it to develop a new cooler. AMD seems to think that the cost of developing a new cooler (higher fixed costs), in addition to the likely higher costs of manufacturing a new cooler (higher dynamic costs), are offset by the potential impact on demand -- they would sell more than enough units to make up for the higher costs, and be in a better position than if they had not done so.

We're still using the same type of cooler, and haven't had a paradigm shift in heat sink design like the Sandia cooler.

With performance, we have an unknown -- it is entirely possible to have a processor that runs hotter, and is more held back by heat than previous designs.

Here's what isn't unknown, though: cost. Costs have come down for raw materials a fair bit in the past few years. Copper is relatively cheap right now, as well as aluminum -- and I'd imagine plastic is as well, given the low cost of oil right now.

Given this, I'd argue that it has less to do with performance, next to nothing to do with advances in thermal management, and everything to do with how inexpensive it must be to make a better performing heatsink right now.

That's a great analysis, but isn't it likely AMD partnered with another company for the fans, rather than developing one from scratch

<BS cut>
No, I like a lot of other people on this forum are just mad because you continuously derail all threads and turn them into personal attacks and flame wars. Like you just happened to do now once again.

Really, what's the point for you in ruining this forum for everyone? Stick to the technical subjects or get out of here and move over to the Off Topic forum where you belong.

Anandtech has an article on this topic now:

http://anandtech.com/show/9925/amd-...ion-cooler-for-microprocessors-in-development



Apparently, AMD plans to offer better coolers with its microprocessors going forward. This week the company revealed its Wraith thermal solution, which will be used to cool down both current and upcoming chips from the company. The AMD Wraith, which was designed to take away around 125W of heat, features a rather large aluminum heatsink with ultra-thin fins, four heat-pipes as well as an 80-mm fan. AMD claims that the Wraith features 24% more cooling fin surface area (179,730.1mm2) compared to its predecessor (144,397.8mm2), which seems like a significant improvement. Contemporary 80-mm fans can generate significant airflow while staying rather quiet. According to AMD, the new fan pushes 55.78 cubic feet of air per minute (CFM), or 34% more than the predecessor (41.6 CFM). The maximum noise level generated by the Wraith cooler is around 39 dBA (based on what AMD says), which is quieter compared to the current-generation D3 cooler from the company, but is significantly louder than noise levels generated by advanced coolers from companies like Noctua or Scythe (20 &#8211; 32 dBA). Overall, the new cooler from AMD seems to be rather efficient for an in-box solution, but only real-world tests will show how good the Wraith cooling system actually is.
[...]
The AMD Wraith cooling system will be bundled with select microprocessors going forward and will also be sold separately. The Wraith should be compatible with all recent AMD sockets (e.g., FM2+, AM3+, etc.), but we are not sure about the upcoming AM4 at this point. Since changing mounting mechanism of a cooler is not that hard, it looks like AMD&#8217;s Wraith will cool down the company&#8217;s chips for quite some time.

I wonder if they will sell these coolers separate from CPUs? I have a friend that would probably like one, but he already has an FM2 APU.

What I don't get is that why they don't make a 120 mm fan model instead. They are much more silent, since they run on lower RPM for the same air flow. But I suppose it has to fit on all motherboards and in all cases. 120 mm fans do not fit on all motherboards if mounted parallel to the motherboard, and not in all cases if mounted vertically. Would be nice with a 120 mm fan option too though.

You dont get why they dont make one, then at the same time explain why it would be silly?

I get why don't make only a 120 mm model, but I don't get why they don't make one as an optional model too. Especially since they intend to sell it separately as well.

They have to compete against a lot of better products. Specially when you remove restrictions so to say. That means very low sales.

And 39dba is...not silent.

Just like their 'successful' RAM and SSD business.

Yup, thus the need for a 120 mm fan... I don't see why they have to make stock coolers so crappy. It shouldn't take much to at least get them decent. And that goes for both AMD and Intel.
You already answered that question. They have to ensure that it will fit in the vast majority of cases.

But it does. Its all about cost and the ability to fit them within required dimensions as you even pointed out yourself.

That's why I said there should be an optional 120 mm variant. Since it's also sold separately there's a possibility for such an optional cooler.

But can such a product compete in the crowd? I doubt. It will be tiny sales at best.

In other words, a product running in the red.

Why not do what they used to do, and just sell OEM CPUs, thus allowing people to save money and buy their own cooler?

Yes, that would be a good option too. At least it should be possible to buy CPUs without CPU cooler. All stock coolers I've gotten included with my CPUs have ended up in the trashcan anyway.

The cooler actually looks rather horrible now.

There is no fan control. Its full speed all the time with the rather loud 39dba idle. Most fans idle at 20-25dba.

Interestingly, the Wraith uses a constant-speed fan that produces 39 dBA at all times. While that may sound like nothing special for a CPU cooler, AMD says that figure comes from testing in its own anechoic chamber. The company thinks that in the real world, the Wraith cooler will be one of the quieter components in a PC. The constant-speed fan could also be less noticeable than a cooler that has to ramp its fan speed up and down often.

8370 will get the fan.

This kind of ruins the product if true. They made a big deal about silent operation.

The TS15A is rated at 40dba at 100%. And I would hate running it at 3850 rpm. Silent is 1000-1200rpm with around 20dba. It can handle a prime95 6700K at 75C with that.

My SG08B case fan is rated for 30dba at full load. And I dont want to run it at that due to noise as well.

To claim the Wraith is silent at 39dba is BS. At 100% is a fine stock number. But without fan control it becomes a serious pain all the time.

Most decent motherboards should support voltage control, but it's still ridiculous to not include a PWM fan on a stock CPU cooler.
