Gelid GX-7It has been a long time since we have had a product from Gelid on the test bench here at Pro-Clockers. But the wait is finally over as we have their newest CPU cooler on tap today. Gelid is known for quiet performance solutions and it continues with the new GX-7 silent CPU cooler. Comprised of seven heat pipes, plenty of aluminum fins and a single Wing 12 PL Blue fan the cooler look to a big performer while not sacrificing your hearing.

Introduction to the Gelid GX-7 CPU Cooler

It has been a long time since we have had a product from Gelid on the test bench here at Pro-Clockers. But the wait is finally over as we have their newest CPU cooler on tap today. Gelid is known for quiet performance solutions and it continues with the new GX-7 silent CPU cooler. Comprised of seven heat pipes, plenty of aluminum fins and a single Wing 12 PL Blue fan the cooler look to a big performer while not sacrificing your hearing.

Gelid’s take on the GX-7

Engineers at GELID Solutions have created an outstanding new CPU cooler with 7 power heat pipes. Contrary to traditional heat pipe arrangement for this GAMER CPU cooler “GX-7”, a special array of heat pipes was used to take full advantage of all 7 heat pipes heat transfer capacity. Further V-shaped aluminum fins were used in the center of the heat sink to allow airflow to reach the heat sink more evenly. Openings inside of the heat sink and near the heat pipes let fresh-air flows in from the top and the bottom to zones normally poorly ventilated, and eliminate the creation of hotspots. The unique heat sink shape supports dual fans.

Closer look

We have review several tower-style heat pipes over the year and some believe that if you have seen one you have seen them all. This is true to a point as the coolers that do share this technology do look similar but some manufacturers redesign the fins, add more heat pipes, make them bigger or even design the cooler to become dual towers. For some coolers these features work and for some it does not. Gelid change to the design was to arrange the heat pipes in such a way where they are stacked and no in line with one another. According to Gelid once a cooler excess five heat pipes had a negative effect on cooling. So, to combat this Gelid soldered two heat pipes on top of three bottom ones.

The GX-7, like we stated above is a tower-style cooler that is cool by a single fan. The cooler fully assembled weighs just 720 grams which is far less than some of the coolers we have tested lately. The height of the cooler is just 159mm, just a few mm taller than the fan that is used to cool it. The stubby structure of the cooler should make it an easy fit in most of today’s PC cases.

From this shot you can see the arrangement of the heat pipes we mentioned above in detail. The number of heat pipes total seven and measures 6mm diameter. At the base the heat pipes are arranged to where two of them are solder atop the other five allowing for all the pipes to be utilized.

The fins are made of aluminum like any other cooler. But on the GX-7 the middle section are shaped in a ‘V’ form. Gelid states that this allows the air to reach different areas of the cooler equally. And the openings in the fins eliminate dead spots.

One of the biggest selling points of the GX-7 is the fan that is used to cool the unit. The Gelid Wing 12 PL Blue was employed to tackle this. The Wing line of fans is known for their quiet operation due to the unique Nanoflux bearings used. The wind-shaped blades help to force over whatever surface it is meant to cool. The fans specifications are as follows: 600-1800 RPM, 10-27 dBA and 75.6 CFM. And did we forget to mention it glows blue?

Stress Testing

For our testing we will be using the following procedures and parameters to acquire the necessary data:

  1. Thermal compound used is Arctic Silver 5
  2. Idle temperatures are recorded after the system has been allowed to idle for thirty minutes from the point Windows has finished loading.
  3. Load temperatures are recorded by running LinX for twenty-five minutes on all available threads.
  4. Real Temp is used for the recording of all temperature sensor reading.
  5. PWM function is disabled via BIOS to allow the fans to run at full speed.
  6. CPU model and overclock speed used for testing are outlined below in "Test Hardware".

Test Hardware:
Motherboard: ASUS P67 Deluxe B3
Processor: Intel Core i5 2500K @ 4.5GHz w/ 1.3 voltages
Ram: Crucial 2133 4GB Dual Channel (9-10-9-28)
Video Card: ASUS Radeon HD 5870
HDD: Hitachi 1TB
Power: Thermaltake Tough Power XT 850 (Sponsored by Thermaltake)
Case: Open air
Cooling: Gelid GX-7

Testing Results


Conclusion

I have never had any doubts from any Gelid products I have tested in the past but I was surprised at the performance of the GX-7. Why? Because if you take in consideration of all the new coolers currently on the market, most weigh well over 800 grams, restrict you from using all four of your DIMM and or considered pricey by many. Well, the Gelid GX-7 definitely does not fit in one of these categories.

The GX-7 comes into the fold weighting a mere 720 grams which is considered a lightweight when talking about today’s top coolers.  Adding in an additional fan added some ounces to the total weight of the cooler but still keeps it over the 800 gram range.

Performance is well within range of being considered good. The GX-7 did well against many other coolers within the same class. And this included coolers from Cooler Master and Scythe. The GX-7 did excel when you add a second fan to the dropping the temps about two degrees. And if you want to take things one step further. Not included in the charts above are temps using the Gelid GC-Extreme which dropped the temps another degree performing better than the Arctic Silver 5 we test all our CPU coolers with.

Price for the Gelid GX-7 is hovering around the $65 area. This put the cooler in some pretty good competition. We believe the price is set at this point due to the fact the cooler is accompanied by a Wing 12 PL cooling fan which cost about $20 alone.
