Best waterblock for A64?

[shuRe]

As the title says really, im pressuming that the G5 is the best, but trying to contact cathar is like trying to contact santa (sorry any kids).

Whats the Nexxos XP like for A64's?

Here is a good review.

[harpyboy]

just aside ... i saw the article... is TDX really that bad ??? i had read good reviews about TDX before i actually got one.... im starting to cry after seeing that article....

[easypanic]

If u can get one of the swiftech blocks, go for it. Very good performers.

[kopeah]

whitewater is really good too.

[Wiggy McShades]

im not sure what ur price range is but the mc6002 performs better than the tdx and its only 45, but they can be hard to find.

[jellybeard999]

cant go wrong with any of the big names tbh...

those few *C wont earn a higher overclock... i wouldnt spend more on a G5 for those 1 or 2 *C less...

[CNCL]

I think it has to do with your pump too, but generally G5 is highly regarded as the best.

[MaxxxRacer]

Shure: to answer your qestion about the nexxos. It is a VERY good block if u have a really powerful pump. it does well with a powerful pump. it still gets good numbers with a less powerful pump but the issue arrises to radiator effeciency and the effeciency of any other blocks with such low flow. The other issue with it is adapting the tiny tubing it uses to something less restrictive.

its essentially this. insane restriction for excelent performance. personally i wouldnt ever use the block but thats just me.

I think a better option would be the swiftech MCW6002 or Danger Den TDX. both are excelent blocks. the mcw6002 lends it self better to low flow while the TDX likes larger pumps more. Either way u go they are both excelent choices.

As mentioned above the whitewater is also a good performing block but the only issue is the 3 barbs. gets kind of annoying for alot of users. but if u dont mind this it is another excelent choice. My only outstanding issue with it right now is that it uses either a acrylic or aluminum top. both of which are poor choices for different reasons. they will soon be coming out with an acetl and copper top which will make the block alot more desierable and useable in a system.

I'm not THAT hard to get a hold of, dodgy email reliability aside.

Still - would not have been able to help you out with a G5 for at least 2 months anyway.

[wfarid]

haha well Cathar has a lot going on and he's all over the place, but i'm getting a g5 from him and the entire process hasn't been that bad... Although I think it wouldnt hurt cathar to hire a secretary or something

edit: overall i have to say Cathar is the man when it comes to wc...

[MaxxxRacer]

lol cathar.. defending urself.. lol...

[bacon]

G4 is going strong here

[notoriousformula]

Mcw-6002/6000

PS: worth every penny*

[xgman]

Get a 6002 for now and order a G4 or G5 as soon as Cathar starts taking orders again. I've had the 6002, the whitewater and curretly a G4. It's worth the wait!

[stardust]

whitewater is very cheap right now.. cooled my old clawhammer A64 cpu @ 2.6ghz and never broke 36dgrees.

[The Mofo]

Got my G4 and im pleased as always with Cathars designs... Funny how everyone copies Cathars materials... :: cough :: Danger Den. Ive got 2 D4's in a series and im sure the spray inside that nozzle is fantastic. Now if Cathar could design a waterblock and rad, we would be set

I am using Nexxos XP now with Alphacool AP 900 pump(900 L/h),black ice pro with 2 12 cm fan (56 CFM) ,2L reservoir and 10/8mm hose

My system A64 Winnie @ 250x10 with 1.48 Vcore
now my room temperature is 30 C ,now my system running D2OL and the CPU temp is 47 C ,i think it is too hot for Watercooler ..or it is normal for Nexxos XP with some issue as you said ?

so any advice to increase my watercooler performance ?

Best water block for A64 is Eddy's MCW:



You can order it gold galvanized too

[MaxxxRacer]

Mofo: cathar did design a radiator. The PA160 from thermochill. I will have one in for review in the next few days.

dimasdw: the waterblock isnt the problem in ur loop i dont think. my theory is it is the supporting hardware. the nexxos XP needs a poweful pump to get decent flowrates. if u dont have one ur flowrates become very low and the effeciency of the waterblock AND the radiator reduces greatly and you have problem.

before you do anything more drastic i would say trying to put slightly more pwoerful fans on the radiator and see what happens. if your temps dont drop down then we know its not the radiators fault.

btw just to remove this from the possible list of things, try remounting the waterblock and checking its mount to make sure it is flat and has good pressure. the nexxos is very easy to overtorque or undertorque (the moutning screw). undertorqueing (horrible spelling skills here) it would result in less pressure than the block needs for good contact thus causing a reduction in thermal effeciency resulting in higher temps on the cpu..

the last possible thing it could be is that u have a borked sensor.. i know my neo2 read my winnie at 52C under load with the TDX, iwaki, and a heatercore.. running at 3.1gpm.. with excelent contact... so it was on drugs.. (still is)


tiborr: though eddy makes good blocks, that design is most certainly NOT the best performing. though if eddy holds it in such high regard as far as performance, when i have time i might ask him to send me one for testing.

[tiborrr]

Regarding the high temperatures with WC:
With my engine rad i was getting around 65-70 degress Celsius on my EpoX EP-9NDA3j which i found hard to believe. But then i installed an 80mm fan @ 5V blowing on the MOSFET area and the temperatures droped instantly to 41°C under full load.

They would probably droped even more if i would equip MOSFETs with some BGA heatsinks and ran fan on 7 or 12 volts.

[MaxxxRacer]

yah just goes to show you how totaly innacurate the temp probes on these mobos are.

[ewitte]

I was wanting to get a G4 but was not able to wait a few months for it. The best IMO (also what I use) easily available block is the 6002. Most places were OOS for the A64 kit so I ordered the Xeon kit and A64 mounting kit.

[amduser]

don't know which block would be best for a us style system, but for a european style system a watercool heatkiller 2.5 would be the best. avaible at www.watercool.de (*cost like 50€*). if you want to get a real good block for 30€ go for a zern pq+.

heatkiller:











zern:

[MaxxxRacer]

amduser that block is amazing. i wonder how restrictive it is.(the heatkiller) i think a relatively simple redesign on it would fee it up alot (that is assuming it needs it)

with the zern does it force the water to flow through those little channels or can it flow above? would be best if it forced it all through teh channels.


i really like botrh of those blocks designs... i wonder if the heatkiller uses the right type of stainless steel so it doesnt cause any corrosion problems.
