Final Words

Effective CPU cooling means lowering the processor temperature compared to the Intel retail HSF which comes with most Intel processors. If an after market cooling solution does not perform better than the kit heatsink, there is no real reason to buy it. A cooler CPU could result in a longer CPU life, but most users upgrade cooling to overclock even further than is possible with a stock HSF. The second characteristic of effective cooling, then, is that it allows a better overclock than the stock HSF.

The Intel Core 2 Duo is unarguably the most overclockable CPU in the current market. It is therefore the logical processor for evaluating the effectiveness of cooling solutions. There is a problem, however, in that the stock Intel retail HSF is really very good at cooling and very quiet. Intel seems to have learned a lot about cooling in working with the incredibly hot Pentium 4 NetBurst processors and they have applied what they learned to cooling the Core 2 Duo, which is not nearly as demanding. This is just to put in perspective the fact that the average heatsink/fan is likely to have a difficult time outperforming the Intel retail HSF. It is a very good kit HSF.

Having said that, it is clear the Tuniq Tower 120 is definitely up to the task. At the highest stressed speeds we could reach with the Tuniq, it still performed better, under demanding gaming conditions, than the Intel HSF at idle. That is certainly not faint praise.

In the second part of our definition, the Tuniq Tower 120 allowed a 200MHz greater overclock than the Intel HSF with the top-line Core 2 Duo X6800. The final overclock with the X6800/Tuniq Tower 120 was a stable 3.90GHz - a 1000MHz boost over the 2.93GHz stock speed. This is with the fastest Core 2 Duo, and we know from other testing that you can get overclocks much higher than 1000MHz with lower C2D processors because your starting point is a lower CPU speed.

For those who also consider lack of noise at least as important as performance we can only say you will also find the Tuniq Tower 120 satisfying. At the lowest 1000RPM measured noise remained below the system floor all the way to the highest overclock of 3.9Ghz. In fact, measured noise generally remained below the system noise floor as long as the fan speed was kept below 1600 RPM. You can squeeze out a few more degrees of cooling at the highest and noisier 2100 RPM, and with some CPUs that will also translate into a higher overclock. Silence is in your control with the Tuniq, since the fan is only manually adjustable, and the kit comes with a slot mounted fan speed rheostat.

From both our criteria for effective cooling the Tuniq Tower 120 is an outstanding CPU cooler. It does what a cooler should do with exceptional performance at all tested levels. Our noise measurements also confirmed Sunbeam's claim that the Tuniq Tower 120 is an "Ultra Silent CPU cooler" - at least at the lower fan speeds.

The performance of this air cooler is beyond reproach, but we did find installation was often not much fun. You have to use a bottom plate for attaching the Tuniq through the Socket 775 mounting holes. This means the motherboard must be removed from the case to install the Tuniq. We wish Sunbeam could find a better way to mount, but we do prefer secure mounting of this large and heavy cooler to an easier solution that might be less secure.

The other issue is the top mounting plate, which must be mated to a pin on the back of the copper CPU mount. It requires a lot of maneuvering to line up those parts and the sharp cooling fins are ready to cut or slice your hand if you're not careful. We suggest you take your time and stop a while if you find you are getting frustrated. Once properly mounted you will be rewarded with some of the best air cooling performance you can find.


Last, many enthusiasts will tell you the smoother the contact surface the better the cooling. Frankly they will not be happy with the relatively rough copper bottom of the Tuniq. If that matters to you, then you will probably want to do a little surface polishing before mounting the Tuniq. An even better solution would be for Sunbeam to provide a more polished mounting surface on future Tuniq Tower 120s.

We have seen comments that claim the Tuniq is the best air cooler you can buy. Others have said the cooling is as effective as many water cooling solutions. We have more testing to do before we can support either of these claims. However, we can say with certainly that the Tuniq Tower 120 is one of the best cooling solutions we have ever tested. When you consider the cost is about $50 the Tuniq also has to be considered an incredible value. We can't think of many other products that cost $50 that will do as much for system performance as the Tuniq Tower 120.

We extend our sincere thanks to Frozen CPU for providing the Tuniq Tower 120 for review. Sunbeam has delivered a deceptively simple product that does what it is designed to do - provide exceptional cooling performance for a wide range of current processors and motherboards.

    The Tuniq Tower 120 weighs 798grams WITHOUT the fan. Both AMD and intel spec ~ 450g maximum and the first-class coolers in this class, the radial design such as the Zalman 9500 and the very similar new Asus radial design endeavor to minimize the weight while maximizing the cooling. The 9500 is ~ 475 grams and the Asus is ~ 610 grams ( both including the fan). Also, the center of gravity of this cooler is much higher off the motherboard than either of the coolers mentioned, especially when the fan is installed. The only way such a cooler can be used safely if the PC is to be transported anywhere after installation... eg to a LAN party or even moving between rooms... is to extend the mounting points of the cooler directly to the PC case, so that the case becomes the prime resistance against any physical strains on the cooler. Otherwise, torsion on the motherboard in the event of any shock to the cooler parallel to the plane of the motherboard is likely to compromise the integrity of the motherboard any one of a number of really nasty ways .... rupture ball-grid array solder joints, rupture circuit-board vias due to layer separation, pop the solder connections of surface mount components, cause hair-line cracks in rigid components such as surface-mount resistors and capacitors. Such failures almost invariably show up as functional intermittents and impossible to track down. I have personally witnessed similar failures caused by poor mechanical designs involving large unsupported components on professional electronic gear when subjected to standard shock tests.

    I've had this installed in my system and i've already moved it about 3-5 times (Lan parties). I've had no issues so far. It seems stable enough.

    798grams? without fan!! i don't think i want that much mass hanging off my mobo.

    The temperature graphs are a bit funny. You give STOCK, 14 x 266 and then 14 x 1095 and 1114 (which I'm guessing are quad-pumped figures instead). Also maybe it was me but I couldn't figure out if your temperature figures were with the Tuniq running at full or minimum speed, I presume the former.

    It's a great bit of cooling but given I'm working in a mATX case, I'll never have the fun of trying this kit out.

    quote:

    The quest for better cooling has been very creative, with solutions as simple as added fans, progressing to larger fans and heatsinks, water cooling, and finally the king of cooling - phase change.


    Did you forget to add Peltier to the list of cooling options?
  • Wesley Fink - Monday, January 15, 2007 - link

    Peltier, or thermoelectric cooling and heating, operates on the same principal as phase change, but the way cooling is actually accomplished is somewhat different. We added Peltier to our list of the various cooling solutions.

    I want to see the temps with just someone blowing on the heat spreader!

    I purchased the new Thermaltake Typhoon VX for my Core 2 rig and love it. I have it turned on to the lowest setting and you can't even hear it. Only thing I don't like is the knob to adjust the fan speed is on the HSF so you have to open up your case to adjust it, they should have provided a PCI slot like the Tuniq to adjust fan speed.

    I read in some review the Typhoon VX is the best, I have the linked saved on my laptop but it comapared the VX to a whole bunch of the air cooling solutions and it performed at the very top. I don't think the review included the Tuniq Tower 120 yet.

    Zalman 9700 vs Thermaltake Typhoon VX vs Tuniq Tower 120 for the next review!!! We would truly know what's best!

    Hi, very nice review.

    I was wondering if you monitored the PWMIC and chipset temperatures too. I had a Sonic Tower (another 'vertical fan' HSF) which cooled my processor very well, but my PWMIC and chipset temperatures were quiet high. I switched to a Big Typhoon where the fan blows down on the motherboard. I had pretty much the same CPU temperatures (actually better) but my PWMIC and chipset temperatures dropped 15-20 degrees C. I was able to remove the chipset HSF and replace it with a passive heatsink and still had lower temperatures on the chipset (minus the high pitched fan noise!).

    Keep up the good work. I check your site at least once a day (yes, weekends too!).

    Thank you.

    We did not monitor chipset temperatures, but you make a very good point. Our EVGA 680i board uses active cooling on the northbridge. Frankly that 680i fan is so loud we needed to turn it off for all noise measurements. It is only needeed for overclocking, fortunately. The 680i is fine with passive cooling at stock speeds.
