PrimeCooler HyperCool III+&4+:
Supplied by: Primecooler

PrimeCooler is a fairly young company, in the last year then have been adding quite a few products; two of their latest cooling products feature 120mm fans and come in a familiar design.

Specifications :

HyperCool III+ CU can be installed on:



* Full copper round design heatsink with relatively small base
* 120mm fan integrated in the center of the unit ( 2500rpm @ 30dBA)
* FAN controller included (5v->12v).
* 645gr

Full specifications at product's webpage.

HyperCool 4+ CU can be installed on:



* Full copper round design heatsink with large base
* 120mm fan integrated in the center of the unit ( 2500rpm @ 30dBA)
* FAN controller included (5v->12v).
* 700gr

In the Box

Each one of the heatsinks comes with a collection of mounting gear, a fan controller, manual and thermal paste. The 4+ adds S775 mounting gear.


Boxed ----- Hypercool 4+ ---- Hypercool III+


Construction :

The HyperCool series looks very similar to Zalman's CNPS heatsinks, there are however a few differences noticeable: the amount of copper (amount of fins), the size of the base, and the make of the fan. The 4+ has more, yet slightly smaller fins (compared to the III+), but its base is sufficiently large to cover the whole P4 IHS. The III+ has less fins and a smaller base, reducing weight and production cost. Both units still weigh less then Zalman's massive CNPS7700-Cu (900gr).


4+ vs III+ ---- base of III+ ---- 4+ vs III+


Base: Top=4+ , Bottom=Zalman CNPS7700-Cu


Installation :

The installation method is identical to the previous versions (and the Zalman series), 2 aluminum bars pass through the Intel retention bracket and the HyperCool unit is screwed tight in them. Motherboards which have capacitors or other large elements around the socket might have problems fitting the massive 120mm fan-equipped heatsinks.




Performance and Noise :

For comparison I've included Zalman's CNPS7000b-Cu and CNPS7700-Cu:



First thing what struck me was the noise difference between the two HyperCool units, I let them run side by side to verify this, and found the fan on the III+ to be considerably louder. Looking at the cooling performance you can see that 200gr less copper translates into 3-4°C higher temperatures, the 4+ offers a good noise/temperature balance. The lightweight III+ has troubles keeping up with the competition but does a good job when the fan speed is set to "Low".

PrimeCooler is expanding their reseller base, but as of now are still much confined to Eastern Europe, hopefully with some International shops sporting their products these heatsinks can become widely available. Priced slightly lower then the competition they offer the end user a budget friendly, yet performing HSF solution.
