Swiftech Apogee XT Rev2 too restrictive?

post #1 of 7
Thread Starter 
First loop being built and I hadnt full understood or researched what restriction does to a loop and now I am concerned. Using martins spreadsheet, my basic loop of a i5-2500k and a GTX 570SC seems to be coming out right abot or just under 1.0 GPM. it would seem the restriction on the apogee is the issue as when I swap that out for say a Koolance 370 or XSPC Rasa, the flow and subsequently the cooling improves.

Am i gimping my loop by going with the Apogee? I chose it because the thermal testing was pretty close on the blocks I was looking at but it has a nicer mounting system.

Do I send it back and get a Koolance or Rasa or something else? How important is CPU block restriction ?

Here are the results of the spreadsheet.

From what I am seeing in that picture, the GPU block is what is restrictive. Granted the swiftech apogee blocks are extremely restrictive. I would highly recommend getting either the EK supreme HF or the XSPC Rasa block. They are the two best blocks on the market, and the rasa is much cheaper then the rest.

.9GPM is fine, I wouldn't worry about it too much. As long as it bleeds ok, it'll give you good thermal results.

And don't use the CPU thermals to compare between blocks. It's meant for comparing possible CPU changes with changes in pumping power, but not for between various blocks.

I have an Apogee XT Rev2 in my system now with the 35X dialed down to 30%PWM levels.

So...I'm sporting about .63GPM and happy with it.. I ran my old supreme setup with a much weaker pump down to an actual .9GPM for over a year.

Bottom line, Flow rate is important to help flush inverted rads of air, but once you get a system filled and operating, you can really dial the flow rates down without any worry.

ok thanks very much, i'll give the XT a shot and swap to a RASA if it causes me problems.

Do I see a Rev2 update or review in the near future? I'd love to go to that from my GTZ, but since flow isn't that big of a factor in reality (and I'm too lazy to want to do the work of rebuilding my loop yet again), I probably won't upgrade even if the XT rocks. I have high hopes for it though, since I'm not sure why, but I'm a swiftech fanboy.

Yes, just finishing the write up...

Looking forward to that to calm my noob nerves.. lol.. between thinking my CPU block might be too restrictive and concern over EK nickel blocks, been worrying if I am buying the right stuff.
