the mcp 35x rpm is pretty much the same as the mcp 350/355 pumps with pwm. most of the guys run them 1500 to less than 3000rpm while its actually capable to spin up to just over 4000rpm

you can google either of the pumps (or the d5/d5 strong) and spent days reading the results. as far as i know, martin is VERY reputable as a reviewer unlike a couple others who took some form of payment for a good review on junk hardware(all speculation to a degree)
thanks mate smile.gif very nice site to have around

"Not electrically or heat dump efficient as PMP-400 (A bit more heat added to the loop)" this makes me wonder how much more heat added to the loop is and if the extra 5ft of pressure is worth the heat gains, sets me back from %100 wanting a pmp-450s!

My thoughts about heating tubing to get it to fit over a tight barb is in a loop disassembly situation.The hose can be close to impossible to get it off.One thing you want to avoid is using maximum physical strenght when your hands are inside your case.There is some pretty fragile components that can be damaged by a pull on a hose that goes wrong.Think about loop disassembly also.

thanks mate, definitely something to consider
however i am still more worried about this "heat dump efficiency"
removing a tight tube is easy with a double edge razor blade! no scratches to the metal if done right

i know someone has to own a pmp-400 450 500 or 450s! i wish they would just post in my thread

i guess being new sucks, hard for people to want to help someone they don't know or care about

lol. no way man. the guys here rock. the water coolers know what its like to know very little and they offer their advice and experience IF they can see you ARE making an effort to find out all you can on your own.
after reading some of martins review, i wouldnt personally choose that pump. it will only downvolt to 11 volts and its actually meant to be run from 12-24v. add to that its a bare pump, nothing included besides the pump, and IMO the value goes down unless you are a hardcore water cooling man/woman

sometimes hard if you know what i mean, it's not like theres a book where you can just flip to the chapter desired
yes, there is google, bing, tongue.gif but when you jump on the pc for a bit and try to do some quick searching and youre gone in 15min or an hour hard to get much done


can i ask why a http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_201&products_id=29201 over a MCP655 or a PMP-500? it seems like such a weaker pump but for the same price redface.gif
edit- is it just because of the low profile/ low watt consumption/ high pressure/flow for a pwm controlled pump or does it do magic biggrin.gif
i guess i dont know how to do the pro's and con's i just keep jumping ship to the fact for the same price i can get "more" pressure and power but im not sure if that even helps

a lot of people run their 655/d5 at setting 3 from what ive read. most people run their mcp355 under 3000rpm.
the 35x is efficient, powerful, and doesnt dump heat in the water. to me, the actual pwm and no additional heat sealed the deal for me to get this come may/june.

im going to shut up for a while. im still a nub and relaying info ive read and gathered. i suggest posting a thread in the watercooling club and gallery listing what blocks and rads you plan to use and ask for advice. good ol' martin may see your post kinda quickly and put in his thoughts. those guys there will all have different thoughts and opinions but they can give some good insight.

don't shut up mate tongue.gif you are only helping not hurting!


http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_318_666&products_id=31134

could i honestly get by with just that reservoir on top of the pump? or should i just replace my acetal bay/res with a

im doing more research on the 35x, im not the biggest fan of the pwm control vs a switch but the key factors you mentioned do make me lean towards it, no heat to the water helps alot

Ok,keep it in mind that you are building a loop that needs to be cut up for tear down.If this is a fact that is accomodated from the beginning you will be fine.I use the Koolance 450 pump (must have bought mine 18 months ago) My feeling is that while heat dumped into the loop is a fact it was not anywhere near the most important fact to consider in loop building.When I started I just ran my 655 variants at max flow and put that issue to the side.I always built loops that went for max cooling instead of best looking.This means that I frequently had most loop components outside the case.This fact allowed for easy disassembly,plenty of cool air and lots of "room to move".My loops were always for folding rigs so I would sacrafice good looks for good performance.I have come to put matching the fan to the radiator as one of my most important features of a loop and do not forget that the board still wants plenty of cool air across it, even if the major heat producers are covered by blocks.

A D5 with a good aftermarket top will last you many years,is very quiet and is high performing.
Get the Strong varient,if you need more push later down the line then get a 24v controller and watch it monster a 35X.
Pressure is not the be all-end all either,Martin himself says the same thing...people dont tend to remember that tho...

Speaking of stupid smile.gif I must go research what the "tops" do, I've never really used or heard of it

Damn seems some are very expensive... almost the price of the actual pump
