When I first received the heatsink, I thought it’s just another Xigmatek HDT-S1283 Heatsink but nevertheless I still gave it a try and I was totally impressed!
Just like the Xigmatek HDT-S1283, this unit was very well built. It comes with copper heatpipes that are in direct contact with the processor, however the advantage of the Sunbeamtech Core-Contact Freezer is that it comes with not 3 but 4 heatpipes. Yes, 4 – U-shaped bent heatpipes that transfers heat from the processor to the aluminum fins.
The Core-Contact Freezer also comes with mounting clips that fit AMD processor setup instead of the 4-pin connector used for Intel’s LGA775. In order to mount this cooler on an Intel setup, you have to first install the 4-pin mounted retention bracket, after that only you clip the heatsink on to it.
The package also comes with an MFDB ( Magnetic Fluid Dynamic Bearing) Fan that boasts silent operation with Ultra-Silent Low-Noise Level (16db) and 50,000 Hours operational lifespan. Unlike the HDT-S1283 that holds the fan via rubber studs, the Core-Contact Freezer holds the fan with metal clips. Yes, just like those you see on other types of heatsink such as those from Scythe and Thermalright.
Besides the fan and the heatsink itself, the package also included a fan-controller (PCI slot mounted unit) and also a Tuniq TX2 thermal compound. 🙂 Talk about a complete package! I only wish that the fan controller was a 3.5″ floppy disk bay mounted unit, but I think I’m just being picky here.
Here are some details…….
|Dimensions(mm)||125(L) × 104(W) × 155(H)|
|Rated Voltage||12V DC|
|Air Flow||90.65 CFM (Max)|
|Noise||16~20 +/- 10%|
|Speed||1,000~2,000 RPM+/- 10%|
|Thermal Resistance||0.092 (? / W)|
Well, it’s a huge heatsink. Just as huge as the Xigmatek HDT-S1283 and my concern was whether I can fit my casing that I had problem closing my side panel due to the HDT-S1283’s height.
And just like any other big heatsink, it’s virtually impossible to install them without removing the motherboard. Yes, I’ve tried mounting the Core-Contact Freezer for about 20 minutes and I finally gave in and decided on dismantling my unit. I hate the hassle, I was using the Albatron PXP35 motherboard and the ATX12V socket placement wasn’t friendly with this heatsink. Nevertheless I managed to get it all mounted (with a bit of bloodshed due to my carelessness).
As for the “moment of truth” (about the closure of the side panel) – the Core-Contact Freezer was tall BUT not tall enough to become an obstruction for side panel closure. YAY!
For the performance test, I just run both my processor cores at 100% load and took the readings. My overclocked Intel Pentium Dual-Core E2140 running at 3.2Ghz was the one to dispense the torture as usual.
Just like the other heatsinks, I’ve LOVE to test them out with out FAN. Yes, I’m a fan of fanless setup. 😀 I was pampered by my Scythe Ninja that ran fanless and held on well to my X2 3600+ @2.5ghz and handled full load without problem. I’ve not had any fanless setup since I upgraded to an Intel setup last year and none of the heatsinks so far were able to take the heat.
Did the Core-Contact Freezer pass the test? YES IT DID! Here are the results, ambient temperature was around temperature was around 25°C when the readings were taken.
|Idle (°C)||Load (°C)|
|Core-Contact Freezer (fan @ max)||25||44|
|Core-Contact Freezer (fan @ min)||27||46|
|Core-Contact Freezer (fanless)||30||48|

Nice eh? I mean really, I’ve been running it fanless for weeks now and it doesn’t fail me at all. The fan itself can be rather noisy when it comes to maximum speed but what I’m most surprised is that it worked so well even without a fan on it.
I love it! Yes, it’s simple as that – It’s huge, it blocked some stuff and I had to remove my motherboard just to install it but in the end it’s just worth it as I have now once again managed to run a fanless setup! 😀
