Top Tier CPU Air Coolers Q3 2015: 9-Way Roundup Review
by E. Fylladitakis on July 6, 2015 8:00 AM ESTThe Raijintek Tisis
Raijintek is yet another new European company, founded in 2013. For a company this new, Raijintek is retailing a fair number of products, which are thirteen coolers, four cases and several fans, with the company now expanding to peripherals and PSUs. The Tisis is Raijintek's most recent and advanced CPU cooler, which was originally baptized "Nemesis" but it was renamed due to a naming collision with another company's similar product.
The Tisis is supplied in a reasonably sized cardboard box with strong black/red artwork on it, focused around a picture of the cooler itself. Inside the box everything is well packed and the cooler is protected inside a polyethylene foam shell. Despite the obviously very rough time our sample had during its shipping to us, everything inside the box was unscathed.
Raijintek kept the bundle to the minimum of things required. Aside from the hardware and thermal grease necessary for the mounting of the cooler and a long L-type Philips PH2 screwdriver, nothing else is provided. It is however noteworthy to mention that there are no wire clips for the fans as this is the only cooler in this roundup review that is using rubber mounts instead.
There are two 140 mm fans provided inside the package, both with a red frame and white blades. There is nothing prominent about the fans, with the exception of the partially jagged blades. The OEM is recognizable and is PelHong Technology, a Chinese manufacturer. Both fans are identical, have engines with sleeve bearings and a relatively low maximum speed of just 1.000 RPM.
The Raijintek Tisis is a very large asymmetric dual tower cooler, with the towers completely different from each other. The fins of the front tower are larger and both of their fan-facing sides are jagged, while the fins of the rear tower are smaller and their sides are completely straight. Furthermore, the fins of the front tower have folded sides, effectively forming a wind tunnel that prevents the air from exiting from the sides. Openings for the rubber mounts of the cooling fans can be clearly seen. This method is a little more convenient than wire clips but it also prevents the adjustment of the fan's height, removing the possibility to raise the front fan a little bit to increase the RAM modules clearance.
The copper base and heatpipes of the Tisis are nickel-plated and polished, especially the contact surface that has been machined down to a perfect mirror finish. Five thick 8 mm heatpipes go through the relatively small base of the Tisis and expand to both fin arrays. For the installation of the cooler, the middle fan needs to be removed, as there is no other way for the screwdriver to reach the base of the cooler.

I know right? I was so looking forward to a W/C vs A/C comparison after an intro like that.Margalus - Monday, July 6, 2015 - link
why didn't you test these all with the same fan? Then we could see how the cooler performed independent of the included fans? Like the Thermalright, it comes with no fan, apparently you got a super quiet slow fan and put on there, but that isn't fair to Thermalright saying they are hotter, when it could be because it doesn't have the amount of air moving over the fins as others.Beany2013 - Wednesday, July 8, 2015 - link
Thermalright provided the fan, so they can't grumble at the results.trandoanhung1991 - Monday, July 6, 2015 - link
When you talk about ultimate cooling, you should've at least tested the True Spirit 140 Power Edition with a TY-143 fan, or the Silver Arrow SB-E Extreme. Those are the most interesting products from Thermalright, not the Macho Zero.Maybe as an addendum at some point? I'm very interested to see how the Silver Arrow and the 140 PE fare against the D15.

Apparently the Macho is what TR themselves chose to send AT, if the intro is accurate... Big /facepalm on their part. They probably have some of the best value coolers in the TRUE Spirits (I have the original Cogage version myself), and the Silver Arrow might've ranked up there with the Noctua and Phantek. The article did make me pretty curious about the latter tho, call me vain but the color choices are cool.Calculatron - Monday, July 6, 2015 - link
Thanks for doing a heatsink round-up. They are refreshing to see these days.It is a shame that Thermalright did not send in its top-tier performer. Then again, the Macho Zero is nothing to sneeze at. ~40C over ambient for a 340 watt load is still a good result. (Perhaps, instead, they could have thrown the TY143 performance fan instead? Har!)

I actually wish they would have sent 2 of the current fans so we could see if push/pull could push it up a performance bracket.rrohbeck - Tuesday, July 7, 2015 - link
I'd like to see the measurements all with the same fan(s) - whatever is considered "the best" fan. That would give an indication of how much you could get out of the cooler with aftermarket fans.'nar - Tuesday, July 7, 2015 - link
I wish there was more review cross-over with water coolers, these two camps seem to be at odds with each other. They never seem to be compared effectively to each other, so it is difficult for consumers to determine the "best" cooler for themselves. With Noctua getting up to $93, there are water coolers out there for less. I bought my Noctua NH-D14 for $75 and thought that was high for a HSF.I strictly used air coolers until I got an AMD APU, among them are several Noctua models. It was apparent to me that this CPU, after a bit of easy O/C, got hot much too fast for an air cooler to absorb. It would crash after just 4 seconds of starting Tomb Raider and the cooling fins were still ambient temperature. I tried three coolers including the Noctua NH-D14. Fan speed did not matter as the rapid increase in temperature exceeded the heatsinks' ability to draw the heat off the CPU itself. I would guess that it take anywhere from 30 seconds to a minute for the heat to actually get to the fins, so if your heat sink cannot "sink" the heat all by itself, no fan, for a full minute, then it has inadequate heat transfer and no fan will fix that.
I installed a Corsair H100i and that works very well. I had previously thought that any cooler with less surface area would have less cooling performance, but I have found that if you cannot transfer the heat to the fins, they make no difference. I think a Corsair H60 would have been fine now. I heard that water coolers were "better" and more efficient, but nobody ever explains WHY.
From this experience at least, it appears that water coolers have better heat transfer performance. Fan speeds and fins are secondary to that, as they do not matter until the heat gets to them. If they get hot, then low speed fans can easily remove that heat as higher temperature differentials generally allow for greater heat transfer. If you run high-power and high-heat for a long time, then higher fan speeds help.
How quickly can your test bench ramp up in power? Was that tested? Was that considered? CPU's can hit maximum power in nanoseconds, and crash in milliseconds. Only the base of the HSF would see anything from that event. I think this test is more academic, and not very relevant in the real-world with actual CPU's. It only tests for maximum heat generation over time, like when running benchmarks, not the dynamic nature in which CPU's operate for most useful loads. But then, that's just my perspective.

I agree with you. I think the heat transfer through heatpipes takes quite some time to get to the fins
