Pros: will fit most cases with 120mm exhaust port at the back, spring loaded tighteners for mounting, offsets ensure you don't over tighten very efficient 120mm radiator. Can cool a moderate over clocked 2nd gen i5 (40% oc) to 65c at full load (prime95) at slightly lower noise levels compared to a mid ranged heat sink and fan. (xigmatex aiger in push pull)

Cons: cooling efficiency not very linear as fan speeds increase (75% fan speed provides near enough the same cooling as 100% possibly could use Higher static pressure fans.) water transfer pipes seem ridiculously thin, they are very stiff kink resistant pipes. could have benefited from larger diameter piping. Not convinced at the pumps flow rate. and think that the thin pipes are there to increase water flow rate which would generally implys the pump has to work harder than it should.

Overall Review: If you want water cooling aio and are willing to spend the time to configure speed fan for optimal performance to noise levels AND you can only mount a 120mm radiator then this is a good option. a h80i is probably slightly better but also slightly noiser. If the tundra 03's cooling performance scaled with fan speeds then i think the tundra 03 would out perform the h80i if you can mount a 2x120 then i would recommend getting something els.td02 or h100i spring to mind as AIO coolers. i would imagine the td02 could also benefit from higer static pressure fans fans too. the one i bought from els where was on sale and cost me £67 in total. i do not think i would have been as pleased with it at a higer price point. in summary. Its a good 120 aio, you need to use speed fan to set the fan speeds up for best balance, could use more static pressure fans. the pump is something i would question the flow rate of. but if you can get one for ~£60-70 its hard to find a 120 AIO at the same price that can beat it.
