Bitspower Leviathan Slim 360mm Radiator Review
Welcome to another Extreme Rigs 360mm radiator review. Today we have another Slim 360mm radiator to put through it’s paces, this time it’s the Leviathan Slim 360 from Bitspower. The full model number is BP-NLS360-F2PB which very closely resembles a model from HWLabs, the NEMESIS-LS-360. Given that HWLabs has been conformed as the manufacturer we are not too surprised at the similarity between model numbers and hints that the Bitspower NLS360 is simply a re-brand of a HWLabs OEM radiator.
In this BP-NLS360 review we’ll be taking a close look at it’s construction, analyzing the performance data and comparing it’s results against the other 360mm radiators we have tested.
Firstly a big thanks to Performance PCs for providing the review sample of the Bitspower NLS360. The support offered by PPCs is greatly appreciated by Extreme Rigs and ultimately means you the reader can make more informed purchase decisions.
What’s in the Box?
The BP-NLS360 sample arrived in full retail packaging which is about as plain as it could be without being totally “brown box”. The all black boxing is consistent with much of Bitspower’s water cooling range, so we aren’t too surprised by the outer retail sleeve design.
Made in Taiwan has us slightly bewildered given that HWLabs (the OEM) is located in the Philippines. Without any confirmation we conclude that Bitspower are supplied with complete HWLabs NEMESIS-LS-360 radiators and only the Bitspower logo is applied by Bitspower in Taiwan. The Bitspower site states that the radiator has a “High Durability Powder Coat in Black Color“, so it is hard to think of any way that Bitspower would be assembling the radiators themselves. Therefore based on our investigating and unconfirmed information, we believe the Made in Taiwan claim is at the very least quite misleading.
If we break down the model number we can be reasonable certain of all but one letter in the “code”
BP: Bitspower
N: Nemesis
L: Leviathan
S: Slim
360: 360mm
F: ?
2P: 2 Ports
B: Black
Removing the outer retail sleeve we find a sturdy shipping box which is sealed with tape that has Bitspower’s logo.
Flipping open the carton we find a very familiar 360mm radiator packaging layout. This is identical to HWLabs packaging and by now this comes as no surprise.
As mentioned in our HWLabs radiator reviews, we wish that there was a bubble wrap bag to protect from scuffs and scratches during transport, but we do like that the supplied accessories have their own compartment within the box to prevent damage to the core.
The supplied accessories are individually bagged and placed in the compartment at one end. Perfect!
Extent of delivery as listed by Bitspower:
Included :
Screws x 1 Set.
However our sample arrived with 2 sets of screws. The thread length of the longer set is 30mm, which differs from the regular 28mm length normally supplied with HWLabs radiators. We believe this is because the screw threads are recessed 2mm so although at first glance it looks like our previous complaints have been addressed, in fact, they have not. More on that later. The shorter screws measure in at 5mm. 
12 screws of each length are provided, so there are enough to possibly install the radiator with either Push OR Pull fans mounted to a case panel, BUT NOT Push/Pull. Notice the word “possibly” in that last sentence. Yes, unfortunately we have on our hands another radiator that has potential to not be installed with the supplied mounting hardware. This possibility is limited to a Push Only fan assembly as intake and depends on the thickness of your case panel or mounting bracket.
For a Push/Pull assembly you will need to acquire another set of longer screws. The actual length required is going to be determined by your case panel or mounting bracket thickness, and as discussed on the following Technical Specifications page, choosing screw lengths for the BP-NLS360 can be tricky and annoying.
Both sets of screws have M4 threads which we prefer over a M3 thread for radiators because it is coarser and (theoretically) able to hold more weight which is of more concern with the larger (and thicker) sized radiators.
Onwards to technical specifications!
Another great and detailed review from you guys.
It’s interesting that the Leviathan *cough* L-series *cough* is noticeably not as good as the 360GTS considering similar characteristics with what looks to be a shroud with inverted sides as the only variation. I was considering getting an L-Series but I think for a small, slim radiator to fit in offset top mounts like my Arc Mini R2 I’d be more likely to look at the Magicool G2 Slim, or Darkside LP360 versus this. The Magicool seems to be a sweet spot radiator for slim versus performance. The original GTS seems to be top but the 133mm width can occasionally cause problems with clearance in cases with said offset top mounts.
I love that you summarize the thermal performance with immediate competition so I don’t have to flip back and forth between tabs to compare slim or thick radiators.
Keep up the great work!
I send all my water cooling buddies here when they ask about “is this enough radiator for my setup?”
