Most ppl end up not using the dial and just leaving it in one spot, lol sort of defeats the point of a variable dial.


what you are saying make sense but i've had issues before with speedfan so i always stray away from pwm frown.gif

im not sure i would the pump fluctuating so much between temperatures, i guess this ahead of my game im still stuck on whether a rad at the bottom will ruin my rad at the top

im trying to find some nice cylinder tubes that arent complicated like the EK which certain ports can only use certain length threads and what not, i really dont want to put rad outside my case :S

edit- im also trying to figure out a way i could mount the monsta 120mm inside the bays somehow, just looking for ideas at this point, figured i might as well not buy something and regret it later

If I was running multiple cards that is the block I would go for in all copper flavor. Has great VRM cooling. Very nice. Those were priced decently as well. Great block for the money.

Best thing to do is look at other builds using the same case. Get ideas on how others have done it before.

Great approach.

I have had regrets and I learn through them. For your case I think a big regret may be not having sufficient radiator cooling and adding a 120mm radiator for inside will offer some cooling peace while keeping all the water cooling in the case.


Because of limited space in your case I think having 1 effective radiator mounted vertically on the back outside would offer the best cooling and allow for nice clean interior and good air flow in case.

Monster 420 would be great externally vertically. If you mount it so that tubes feed at bottom you will not need a reservoir. The Radiator mounted vertically with flow at the bottom will work fine to feed the pump. Have the radiator mounted externally will offer great air flow and will allow for easy servicing. It's a little pricey but you will not have to buy reservoir or extra barbs for reservoir.

420 May be hard to mount with tubes at bottom because the PSU may be in the way. Not sure how tall your case is. A monsta 280 may fit just right and should work great for single CPU and GPU.

b-gear 140mm fans are good for the money. Push/pull ... These on a controller for noise and performance control.

This fellow says the EK water block has the worst performance between heatkiller and komodo, any thoughts guys? smile.gif

You should look into the members posts that are giving you advice and deem whether its reliable or not. Don't just take whatever John Doe says as fact. THere's lots of ppl giving out advice like they've been there first hand when they have not.

I actually prefer the ek because i love the balance between gpu cool and vrm cool.Actually ek blocks have one of the best flow out there.Its dumb to say that

That Bundymania review was awesome but it didn't list VRM temp data and IMO that is very important because HD79XX cards put out alot of heat on VRMS and good VRM temps is very important.



I have seen good VRM temps posted by many original EK blocks (1st version) and that block is well built and does offer great gpu cooling. That EK block strong point is the high flow rate which makes it the best block for multiple gpu card cooling.


If you like the Komodo get the Komodo. You are only running 1 card and it should work out well for you since you like the appearance of it. If you want the more effective single block get the Heatkiller since you also seem to like that one. The performance between these 2 blocks is very close the Heatkiller does perform better based on the review and I have seen many positive results from the Heatkiller.

^^Adding to the above, was going to post this actually but forgot but luckily it was still in cache.



Btw I used these 7970 blocks, ek, heatkiller, aquagrfx. Ek has issues like all blocks, but they make up for it a few ways that NO OTHER blocks can touch. They have the best fitment, bar none. If you clamp a board down on aquagrafx/heatkiller block, you will warp your board however minutely it will bend. On an ek it will lay as flat as it can get.

Ek also as the best vrm cooling channel design, BAR NONE. This is not up for debate. Also, Bundys tests are rather weak and did not test vrm temps, big fail. There's a couple tests on the ek block and the vrm temps are superb. I have to find the link since I misplaced it.

Also, the v1 ek block is the best looking block till they got all X files with the crop circles, grr...
