This time we tested TherMax Eclipse CPU cooler from Spire. It has a tower design with five copper U-shaped heatpipes and comes with two 120 mm fans. But how will it perform?
Eclipse box is made of card paper, with a front window that allow you to see the one of the fans, as you can see in Figure 1.
In Figure 2, you can see the box contents: heatsink, fans, instruction folder, installation hardware and a tube of blue thermal compound.
In the next pages we will analyse this cooler in detail.[nextpage title=”Spire TherMax Eclipse”]
In Figure 3 you have a front view of the heatsink. It looks sturdy with thick fins and well-distributed heatpipes, everything nickel-plated for a nice dark metallic looks.
In a side view you can see that the fins are folded, don’t allowing the airflow to escape by sides of the cooler. But we’ve already seen a cooler with a similar heatsink: iCEAGE Prima Boss II.
In a top view you can see the position of the heatpipes and the shape of the fins. Actually this heatsink is practically identical to the one found on iCEAGE Prima Boss II.

TherMax Eclipse comes with two fans, shown in Figure 6. One of them has only a three-pin connector, intended to be plugged on the motherboard, while the other one comes with a three-pin connector and a standard peripheral four-pin connector, so you can plug it directly to your power supply, if your motherboard has no fan power connector available. Unfortunately, none of them have automatic PWM speed control. TherMax Eclipse also does not come with any type of fan controller.
In Figure 7 we can see the rubber fan holders, also like the ones found on iCEAGE Prima Boss II. These holders are very soft in order to absorb all the vibration generated by the fans.
In Figure 8 you see the base of the cooler, smooth but with no mirrored finishing. Heatpipes keep direct contact with the CPU.
To install TherMax Eclipse you must use a backplate, shown in Figure 9. The screws must be first installed in the correct holes depending on your CPU socket.
Figure 9: Backplate with screws.
After installing the backplate on the solder side of the motherboard, you must put the cooler over the CPU and fasten it with four thumbscrews. Only after that you can put the fans in place.
Figure 10: Installed on our motherboard.
In Figure 11, you can see the fans in place.
In Figure 12, you can see TherMax Eclipse installed in our case.

[nextpage title=”How We Tested”]
We are adopting the following methodology for our CPU cooler reviews.
First, we chose the CPU with the highest TDP (Thermal Design Power) we had available, a Core 2 Extreme QX6850, which has a 130 W TDP. The choice for a CPU with a high TDP is obvious. To measure the efficiency of the tested cooler, we need a processor that gets very hot. This CPU works by default at 3.0 GHz, but we overclocked it to 3.33 GHz, in order to heat it as much as possible.
We took noise and temperature measurements with the CPU idle and under full load. In order to achieve 100% CPU load on the four processing cores we ran Prime95 with the "In-place Large FFTs" option, and three instances of the StressCPU program, all at the same time.
We also compared the reviewed cooler to the Intel stock cooler (with copper base), which comes with the processor we used, and also with some other coolers we have tested using the same methodology.
Temperature measurements were taken with a digital thermometer, with the sensor touching the base of the cooler, and also with the core temperature reading (given by the CPU thermal sensor) from the from the SpeedFan program, using an arithmetic average of the four core temperature readings.
The sound pressure level (SPL) was measured with a digital noise meter, with its sensor placed 4" (10 cm) from the fan. We turned off
the video board cooler so it wouldn’t interfere with the results, but this measurement is only for comparative purposes, because a precise SPL measurement needs to be made inside an acoustically insulated room with no other noise sources, which is not the case here.

On the tables below you can see our results. We ran the same tests with the coolers shown on below tables. Each test ran with the CPU idle and the with the CPU fully loaded. On BigTyp 14Pro, TMG IA1, NH-U12P and ISGC-300 the tests were done with the fan at full speed and at minimum speed. The other coolers were connected directly to the motherboard and it controls the fan speed based on CPU load level and temperature on PWM models. ISGC-400, iCEAGE Prima Boss, Megahalems Rev. B, Thermaltake SpinQ VT, Zalman CNPS10X Flex and Tuniq Tower 120 Extreme were tested at minimum speed on idle test and at maximum speed on full load test.

At first look we thought Spire TherMax Eclipse would be an excellent performer. Its construction quality impressed us and with five heatpipes and two fans it looked like we had a winner in our hands. After we realized it is virtually the same cooler as iCEAGE Prima Boss II – which performed very well in our tests – we got even more confident.
But the results from our tests surprised us, showing a mediocre performance. We checked the installation, looking for some error like an inverted fan or something of this sort, but it was all fine. Some readers could ask about the curing time of the thermal compound, but this could not produce a difference in our results that big and all other coolers were tested with no curing time. By the way, we are planning on a comparative test with different thermal compounds and we wish to make some experiments to know if the supposed advantage of a curing period is a fact or a myth.
TherMax Eclipse also has another problem: it has two strong fans without any kind of speed control. If you like silence, you must buy a fan controller as a sidekick for this cooler.
Therefore TherMax Eclipse is not a good cooler. Maybe not it is not a coincidence that
Spire released TherMax Eclipse II, a product virtually identical to the model we tested, which may mean that the manufacturer knows about the low performance of the first version and improved it in a second incarnation.
