Not long ago we took a look at a couple GlacialTech 5610 Series CPU coolers, they are the smaller sized heatpipe variety and overall they are a decent performing cooling option. Today I've got two more CPU coolers from GlacialTech, these are the 5750 Series and they are much larger, offering 4 heatpipes, dual 92mm fans, a choice of silent or PWM versions and they should prove to be a great performer. So continue on to learn more about these CPU coolers…

GlacialTech Igloo 5750 PWM and Silent CPU Coolers
IGLOO 5750 PWM CPU cooler and IGLOO 5750 Silent CPU Cooler for both Intel LGA775 Socket CPU’s and AMD 754, 939, 940, AM2 & F Socket CPU’s. The unique design for the enthusiast incorporates a specially aligned aluminum heatpipe combination of four pipes that dissipate the heat from the CPU directly into the heatsink fins. From there, the Silent version’s double fan quietly and efficiently brings the temperature down. The low decibel (19dB), high volume (30.8 CFM) fans are 92mmx92mmx25mm and run at an ultra-quiet speed of 1800 RPM. The dual fan is a unique concept that not only cools down the radiator, but the added blow down effect also cools down the heatsink directly above the CPU.
Unlike the Silent version of this series, the PWM version has a dual 92mm×92mm×25mm adjustable speed fan setup which brings the temperature down according to your needs, The fan ranges in speed from 800~2500RPM, with a maximum volume throughput of 51.3CFM. The Fan puts out 34dB maximum at full revolutions. The entire heatsink (both versions) keeps a relatively low profile and only weighs in at 507grams, making it safe and light enough to pose no danger to your Intel CPU. (Designed to comply with weight regulations of 550 grams on Intel CPU’s)
The IGLOO 5750 PWM or IGLOO 5750 Silent CPU cooler gives you far more efficiency than competing products for your enthusiast PC platform.
With today’s power hungry computers, GlacialTech has implemented a cost effective and useful way to keep your processor cooled. When doing resource hungry applications and you have the PWM version installed, turn up the RPM to 2500 to manage your heat dissipation more effectively. While the PC is in idle or doing non-intensive work, turn the RPM back to 800. In this way you manage your power consumption, your decibels and your overall peace of mind. Alternatively users have the option to purchase the Silent version; GlacialTech gives you the variety and options to suit your needs.
As a total thermal solution provider, GlacialTech is committed to bringing increased value to customers in a quiet working environment. The IGLOO 5750 PWM and IGLOO 5750 Silent are the next step in your evolution to an ultimate light weight, low cost CPU cooler for your system.

A Better Look at Things
:
The GlacialTech Igloo 5750s come in a rather nicely made box with their own little carrying handle built in to the tops of them. There is a small cutout window on the front of the boxes allowing you to get a glimpse at the cooler, and of course the box has lots of information about the specs and features listed as well.
Inside the box we find another plastic box which house the cooler and it's parts, along with that is the installation manual. The coolers come pre-installed with the brackets for installation on the Intel 775 platform, with the other mounting hardware included in a bag on the side.
Here's a couple shots of the GlacialTechs next to the stock Intel CPU cooler to give you an idea of the size for reference:
The coolers feature a gold colored fan shroud over the fins with the GlacialTech name on two sides. The fans are actually spliced together to one 3-pin fan connector or 4-pin on the PWM version, which is something I didn't expect at all, I expected two connections. The two fans are mounted in a push-pull configuration, one on top and one on the bottom.
The base features another smaller heatsink as well mounted on top of the heatpipes, or the heatpipes are sandwiched between the base plate and the heatsink.
As I mentioned these coolers come pre-installed with the LGA775 bracket, which can be easily swapped out with the use of a screwdriver to use on another platform. They come with thermal compound pre-applied so of course care must be taken when handling them. While it is difficult to get a good look at the actual base with the thermal compound pre-applied, it did appear flat, but not a smooth finish, fine machine lines are visible in the base.
The coolers feel well made, and for their size they are actually not that heavy, they look much heavier than they really are. One thing I did notice is that the heatpipes seem very flexible so care must be taken when handling and installing these coolers so not to bend and/or break the heatpipes.
Installation, Testing and Comparison
Heres's a couple shots of the two GlacialTech Igloo 5750 cooler side by side:
For testing I had both of these coolers installed for one week each.
My test setup consists of:
Intel P4 Extreme Edition 955 CPU @ 3.46GHZ
Gigabyte GA-G33M-DS2R LGA775 Motherboard
Crucial Ballistix Tracer DDR2 PC2-8500 (2x1gig)
Connect3d X1800GTO Video Card
Ultra X3 800-Watt Modular Power Supply
1x hard drive
1x dvd/rw drive
2x 120mm case fans, (1 intake and 1 exhaust)
all housed in a Thermaltake Matrix VX case
Installation for the most part was easy, since these are the standard push type mounts I didn't have to take the motherboard out of the case to install them. I did find though that getting the top left corner (corner where power supply and fan are) lock was a bit difficult as space was very tight between the heatpipes and PSU. There are no clearance issues or any other problems to report with installing these coolers.
Here's a few more close up shots, you can see there is plenty of room around these coolers.
To get temperature results the system was stressed using Orthos Stress Prime for 30 minutes several times a day and the results recorded, then averaged out to what you see in the graph below. To get my idle temperatures I turned the system on and let it sit doing nothing for the same 30 minute time period.
Ambient room temperature during all testing was approximately 20.6C.
In the following graph you'll see results for both GlacialTech coolers, there are temperatures when having the fans connected directly to the mother CPU fan header and connected to a Molex connection via a 3-pin adapter with fan speed sensor lead. Included in the Intel Stock cooler, the Noctua NH-U12P and Coolink Silentator for reference as well.
You'll notice some pretty high temps while connected via PWM, I noticed the fan speeds didn't get over 1100RPMs under load, and ran at about 800RPMs at idle. Supposedly these fans are supposed to hit 2500RPMs at full speed, I checked my settings in the BIOS and I did have PWM enabled so I'm not sure what was going on there. I actually thought maybe the cooler wasn't mounted correctly, but as soon as I switched to the Molex connection I saw the temperatures drop drastically as you can see from the chart.
The 5670 Silent version experienced the same type of cooling differential with the motherboard fan header and the molex connection. While connected to the motherboard the fans never went over 800RPMs, but connected to the molex they ran at the rated 1400RPMs which of course increased their cooling efficiency.
The fan of the PWM version while connected to the CPU header were virtually silent but while connected to the Molex, running at full speed they were audible, but not overly so, more of a low whining sound. The fans on the Silent version of the 5750 are virtually silent no matter which type of power connection I used, which actually surprised me having two fans running at 1400RPMs and still being quiet.
Seeing as these coolers (especially the Silent version) perform better while running connected to a Molex connection one has to wonder why GlacialTech did not include a 3-pin molex adapter with them in the package? Sure you can go into your BIOS and set the fans to run at full speed or even possibly use a software program to do this but why when you can just hook them up to the molex connection? Also, depending on the users level of knowledge they might not be able or know how to go into the BIOS and change these settings, or may not even have the setting to change in their BIOS…
Personally I'd be inclined to use a better thermal compound as well, I'm sure if I would have put AS5, MX-2 or similar high performance thermal compound on these coolers they would have had an even better performance…
Summary:
Overall the GlacialTech 5750 Series coolers perform well and do as advertised, they look great and are very easy to install.
While they may not be the best cooling in my comparison, as I mentioned I've a suspicion it has a great deal to do with the thermal compound that was used with them. I believe using a high performance thermal compound with these coolers would make a big difference in their overall performance.
DragonSteelMods gives the GlacialTech Igloo 5750 PWM and Silent CPU Coolers a 4.5 out of 5 score overall.
Pros:
-Easy installation
-Quiet
-Well made
-Aesthetically pleasing
-Good performance
-Multiple platform support
Cons:
-No Molex adapter included
-Heatpipes flex easily, care must be taken in handling and installation
