GlacialTech started in 2001 when eight PHD researchers specializing in thermal theory and three factory owners came together to form a total thermal solution provider. Since then the company has taken light weight materials and merged them with low noise parts whilst using a low cost manufacturing process to deliver low cost high efficiency products. As of today GlacialTech has produced power supplies, HTPC and server chassis', fans and also one of the types of products we will be looking at today, CPU coolers.

The GlacialTech IGLOO 5610 Series is much like the 5710 Series we looked at just a few days ago, two identical heatsinks with the choice of fan as the variable that makes up the Silent and PWM version. The 5710 we looked at featured three heatpipes, and the 5610 we will be testing today only has two.

The specifications for the 5610 is lower than that of the 5710 so we are not going to be looking at stellar performance numbers, but honestly how low can a product line go. The 5710 were not great performers and border the low end of what a modern day CPU should use for aftermarket cooling performance. With that said though, let's have a look at the specs and see if the GlacialTech 5610 can surprise us.

Specifications, Availability and Pricing

Unlike the 5710 we looked at previously, the 5610 Series is not a universal cooler. Intel Socket 775 only for this round from GlacialTech; AMD Sockets need not apply.

The specifications listed on GlacialTech's site only show the Silent version so the PWM model is somewhat of a mystery. In the above image taken from GlacialTech's site you see two red stars; this indicates that system chassis airflow must be optimal to use the 5610 with these CPUs. The CPUs listed are Intel's hottest parts to come out in the last couple of years, so if your Intel processor is either a Pentium D 3.4 GHz or an Extreme X6800 you are being warned by the manufacturer that bad things will happen without adequate case cooling.

The 5610 Silent has an MSRP in the US of $24.90 USD and the PWM model is set at $27.40. At these price points the 5610 Series is one of the lowest cost aftermarket CPU Coolers available today, but it will still have to compete against old stock coolers that are left over in limited quantities from large discount e-tailers.


The Package

As you can see the box is the same for both the 5610 Silent and 5710 PWM. On the front you can see a product image as well as clearly marked Intel Socket T CPU Cooler.

The side of the box designates if you are purchasing a Silent or PWN model.

On the back GlacialTech has listed the processors that the 5610 is compatible with; unfortunately there is not a red star listed here so hopefully the home OEM builders will read up on the cooler before they go frying Intel's hottest CPUs.

The other side doesn't list anything other than the usual CE, RoHS, do not throw away and this box is made from recycled paper information. Maybe someone forgot to put the red star information on this side of the box?

The Cooler

Although menacing in this close up picture with the 80mm eleven blade fan the 5610 is only 99mm tall. The 3-pin connector shows that this is the Silent model.

From the side you see the two heatpipes that start at the bottom and move up into the aluminium fin area. On the bottom you can see the aluminium heatsink that rests on top of the heatpipes at the base.

Here you can see the heatsink that sits on the heatpipes at the base better. These are actively cooled by the 80mm fan.

The other side of the cooler is identical to the side we have shown you previously.

Here we see the Silent 3-pin power connector and the PWM 4-pin connector. The 5610s both use a 12 inch wire lead so reaching the correct power plug on the motherboard shouldn't be a problem.

The Silent is on the left and the PWM is on the right. Both of the fans appear to be identical other than the power connector. PWM fans are dynamic and change RPM based on sensors on the motherboard and on the fan.

Both models come from the factory with a coat of thermal compound pre-installed.

After removing the factory thermal paste we see that the 5610 does not have a mirror like finish.

Accessories and Documentation

As for accessories you receive a special back plate that is needed to mount the CPU Cooler. Motherboard removal is guaranteed since the cooler uses a proprietary mounting mechanism.

Here you can see the heatsink screwed into our TECC test board.

The manual for the 5610 Series is a simple one page step-by-step photo enhanced walk through.

Testing Results

Test Results

TweakTown uses a different method for testing CPU heatsinks which allows for an even playing field across all product tests. We feel that by using the same ambient temperature and strict lab-like testing procedures we are able to accurately compare one product to another. More information on our testing procedure can be found in the T.E.C.C. article here.

Both the PWM and Silent Versions of the 5610 deliver load temperatures that are higher than the stock retail coolers from both AMD and Intel. The same is true for the idle tests, it is clear that there is good reason for GlacialTech to include a warning on the website for high-end CPUs. Granted our testing mythology is geared towards these high-end CPUs, but at these temperatures even stock speed mid-range CPUs could fall into trouble without good case cooling.

Our SPL testing shows the 5610 Silent to be one of the best coolers we have tested when it comes to acoustic footprint. With such a drop off in sound compared to the PWM model it is hard to see how the Silent only loses a little bit of ground when it comes to performance. Clearly when it comes to the two 5610 Coolers the Silent is the way to go.

Final Thoughts

Our testing is geared towards the luxury high-end CPUs so coolers that are designed for the lower end of the scale don't look very appealing when put into this type of apples to apples format. The GlacialTech 5610 Silent and PWM are the lowest priced coolers we have tested to date with an MSRP in the mid 20 Dollar range.

Would the GlacialTech 5610 be a good choice for the lowest speed binned Intel processors? With a non overclocked Core 2 Duo or Celeron Series it would certainly be a choice, but from our testing the stock Intel CPU Cooler would be a better option. Many processors are sold as OEM or tray style units without heatsinks and this produces the need for a low cost (and in this case low performance) heatsink.

Overclockers, enthusiasts or just about anyone using a high speed processor will want to steer clear from the GlacialTech 5610 PWM and Silent. I really wish GlacialTech would have included their disclaimer on the retail box about high-end processors, in my opinion this information should be added on the next round of box printing and a sticker sent out to distributers to attach to current stock. With the numbers we encountered from our testing permanent damage could result from using this cooler on an overclocked processor or any quad-core part running at 2.6 GHz or higher.
