CPU Cooler Final Thoughts

There is one minor drawback to using the Core i7 or Phenom II processors which affects overclockers: the difference in CPU cooler mounting dimensions. Many overclockers and enthusiasts have grown to cherish their favorite cooler, and trust them to cool the hottest system they can build. The problem is that now many manufacturers are offering free adapter kits, or include an adapter with their current model coolers, which leads to bigger problems because of processor differences. For all of our LGA1366 test products, we used the Xigmatek ACK-I7361 or ACK-I7363 CrossBow bolt-through mounting kits whenever possible.

Heatsinks made for the old LGA775 platform are designed for use with a Core 2 (Duo or Quad) or Pentium 4 and D processor with an integrated heat-spreader measuring 28.5 x 28.5mm (812.25mm total area), but the LGA1366 socket requires a much larger 32 x 35mm (1120mm total area) footprint to accommodate the extra 591 'pins'. Then there's the LGA1156 socket, which measure 30mm square for 900mm of area. If you use an LGA775 or LGA1156 cooler on a LGA1366 socket, your missing out on up to 38% (307.75mm) of the contact surface. Additionally, the cores are located in slightly difference locations; the Core 2 Quad is slightly spaced away from the center, while the Core i7 is concentrated there.

The Phenom II processor series from AMD offer a very large 37.31 x 37.31mm (1392.04mm total area) integrated heat-spreader surface, which is the largest processor surface I can recall since the original Intel Pentium (I) days. Compared to Intel's Core 2 Duo and Quad processors which measure 28.5 x 28.5mm, the Phenom II offers over 71% more contact surface area. If you compare the latest Intel Core i7 processors which measure 32 x 35mm, then the Phenom II series offers 24% more contact surface area. For overclockers, this will mean a much larger area to cool, but also much more manageable temperatures.

There are a lot of different products out there, and believe it or not we exclude a few from each article because they don't stack up well at all. So this is why you may not see some of the coolers other sites have tested in our results. Because of space and time limitations it's just simply not feasible to review them all, but it's certainly worth mentioning which products should be avoided. So I began to carefully think about it and nearly constructed a real-time chart which places products into different levels of performance. That's when I realized that performance is relative, too, and what performs well today might be considered low-end only a year from now. Perhaps the best method for testing is to use a synthetic system to generate the same exact load for each and every test conducted. This would stand the test of time much better than any computer system or processor platform would, because temperature is a static measurement, but it wouldn't take into account the differences seen between processor model architecture.

The synthetic test unit might generate 250W of thermal energy, but every CPU series has a different layout and might not mate perfectly to a particular cooler. This brings me to my final point: there's a cooler for every processor and purpose. The ordinary casual computer user is fine with the included thermal cooling solution that comes with the retail processor kit. Systems built with a Core 2 Duo processor and three-piped HDT cooler (like the HDT-S1283 or Vendetta 2) will not be cooled the same as a Core 2 Quad processor because of where the cores align with the heat-pipes. Likewise, coolers built around the Core 2 LGA775 design may not perform well at all with the Core i7 or Phenom II platforms. This is why the research is so critical, and understanding the product is important.

I´m puzzled about V6 GT heatsink,what caused the loss in performance? Could it be the fan has less CFM?? Or it is the static air pressure?? or another thing that i cannot think?
Aside from that great test, as good as always, and still help me emphasizing that i did a good thing buying scythe mugen 2.

There's no doubt that the Mugen 2 was a good investment... it's a great cooler for very little money. The V6 GT has two high-output fans on it to begin with, configured in a push/push set, so it's understandable to see performance decrease with one higher-output fan.

# RE: FanDavid Ramsey 2010-07-27 19:21
It's simple: the Cooler Master V6 GT's stock fans provide a lot more airflow than the single Yate Loon fan. Base on the fan specifications, airflow drops by about 50% in this case, so the cooler's performance suffers. The V6GT represents a design trend in coolers that provides good performance with a relatively small heatsink by simply pushing a lot of air through it. You'll probably see more of this, since plastic and fans are cheaper than copper and aluminum.

Either lots of plastic and fans, or pretty copper fringes to make you feel better about the premium price.

Don't forget to paint it black to get extra premium performance...

# Vertical motherboard test?Testy01 2010-07-27 20:03
It appears these coolers are designed for horizontal motherboards as heat rises. Surely using a system in this orientation with aftermarket or supplied fans will give a better outcome.

Vertical motherboard means that it stands upright, as in the case of most all mid-tower enclosures.

The V6 simply doesn't have what it takes to be a top notch product. Its too small and the build quality is not very good. The problem is if you turn the stock fans down performance figures will drop pretty quick.

Sure it does. The build quality on the sample I tested was excellent-- flat, well-finished base; perfectly ven fins, and nice little details like the rubber anti-vibration pads on the snap-on shrouds that hold the fans. The stock V6 fans are PWM controlled, so let your motherboard decide how fast they should be run, and you'll get a very good combination of balance and noise. The performance with the stock fans is excellent, too. My only complaint about the cooler is its high price.

How come the Titan Fenrir was in instead of the Thermaltake Frio? The Thermaltake Frio did better than the ProlimaTech Megahalems in stock fan test and a little worse than the Mugen 2 with the Yate Loon D12SH-12. Are you using one or two Yate Loon D12SH-12? I'm sure I'm not the only that would like to see temperatures with both one and two high-output fans on there.

# RE: ?Olin Coles 2010-07-28 07:05
Usually it's because of time contraints. If we had unlimited time, every single heatsink ever made would be tested for each article... but that's just not the case. We've already reviewed the Frio in our cooling section, so take a look there: benchmarkreviews.com/index.php?option=com_content&task=view&id=519&Itemid=62

It would be awesome to see pictures of the heatsinks in the computer setup in the future, I tried my thermaltake frio with the air blowing up but it blocked the first 2 ram slots, so I had to turn it where it blows outside the case since the computer would be faster in dual channel mode than single channel mode

Are there any plans to do a similar review, maybe smaller in scale, for those coolers that use 92mm fans instead? Reason I ask is that some mATX cases like the NZXT Vulcan have clearance issues with a good many 120mm systems even with the added room of special side panels. Consider as well that many have even released revised designs that will work on LGA-1156 and LGA1366 sockets including those from AMD with a sample list here:

ARCTIC COOLING Freezer 7 Pro Rev.2
COOLER MASTER Hyper N 520
Cooler Master Hyper TX3
Noctua NH-U9B SE2
Scythe "NINJA MINI Rev.B"

Granted, there are individual reviews for some of these out there but let's face it they're not you guys. ^_^

I have wanted a writer to take on the 92mm segment for over a year now. Apparently the threat of constant work with unreasonably tight tolerances has dissuaded everyone on staff. That and it's boring beyond belief. Still, I have my hopes.

I would love to see a system for rating the mounting hardware on each review. There are a couple heatsinks I'm really liking but the hardware uses pushpins (Cogage True Spirit) or is a mini erector set (Mugen 2). I really think a Cogage True Spirit with ProLimatechs brackets would be the best.

# Can we get CPU Perf for LOW PROFILE Collers?OneEyedPony 2010-09-10 11:35
These big brick sized CPU coolers are great for the monster and mid towers, BUT...

I deal in building small cased PCs for people. I would like to see recommendations for CPU coolers in the 50-100mm height range.

# Low profile?RealNeil 2010-09-28 05:23
Corsair H50,.....Asetek LCLC (they actually make the H50 for corsair) and the ECO A.L.C. ECO-R120 CPU Cooler. All are water cooling solutions and all are relatively low profile.
I have two of the Asetek LCLC's (stands for: Low Cost Liquid Cooling) here and they work really well. I added extra fans to both of mine for a push/pull effect. I also have a Scythe Big Shuriken SCBSK-1000 120mm CPU Cooler on a Linux box and it's a very low profile cooler.

"Because of their density, metals are the best conductors of thermal energy"

Actually that's wrong the best material is Diamond but an HS made of diamond would cost and absolute fortune.... you should have said best Perfomance/cost material is metal of which the best is Gold (best $$$$/Performance = Copper)for now atleast until they make Carbon nano tube materials more readily available
