DIYhz Water Cooling Computer Radiator, 12 Pipe Thick Copper Heat Exchanger Liquid Cooling Radiator G1/4 Thread Heat Row Sink 360mm for CPU PC Laser Water Cool System DC12V Black

I have held off on buying a budget PC radiator for a while. I have heard all sorts of stories about radiators coming in brand new with leaks, etc. To be honest this terrified me. Who the heck is building radiators that leak brand new!? If you manufacture these things at all they should not leak new as they are simple devices. Anyway I am happy to say this one didn't leak and the item looks exactly as advertised in the image. The paint is blemish free and the radiator itself is well constructed with no damaged fins or other manufacturing anomalies. Also there are screw mounting holes for 120mm fans that match spec perfectly, for fans that follow spec that is. As the manufacturer warns don't screw in too deep otherwise you will puncture the radiator. I kept it to a few mm.NB: The system described is not a typical PC cooling setup (what this radiator is marketed for) and can result in electrocution and death if done by persons not aware of the risks who do not take the proper precautions. I am outlining testing conditions that are generally much more extreme than a user would typical put this unit through for information purposes only.I am using this in a low pressure, high volume loop system...the driving pump is pushing 800 GPH of tap water through this radiator while running into a recycling reservoir where processing on it occurs. I am running through 20ft of flexible hose which has accidentally partially kinked on the return a few times driving up internal radiator pressure slightly. I have run it for hours on end and in short bursts for a couple of minutes. All operations have been conducted at temperatures ranging from around 35.6 F (2 C) to 104 F (40 C) with the bulk of operations occurring around ~80 F (27C). The radiator is still holding strong after about 2 weeks of this. Water sits idle in it for hours at a time when the pump isn't running so this is also my corrosion test. My application has water partially draining from the radiator sometimes leaving air voids. These voids are then driven out by the pressure in the pump when it is activated. This sort of light "bubbling" can definitely cause a badly constructed radiator to break loose a badly folded pipe seam, etc. so you could say I have definitely stress tested this radiator! If it is constructed the way it is advertised it should last a long time. I am not exceeding manufacturer specifications.Only time will tell on the longevity of the radiator and I will update in the future. However as of now after 2 weeks of full use I can safely say I would buy this radiator in a heartbeat again. It is exactly what I envisaged when I purchased it, a quality radiator for a good price. Copper cores may be nice but copper core prices aren't (most are seriously over priced). With my flow volumes I am using aggressive water cooling more than simple heat convection so this is exactly what I was looking for. Just because a product is targeted to a hobby market than doesn't mind wasting a lot of dollars doesn't mean a company like this can't come in there with a budget solution and produce a good product at a FAIR price. Modern radiator technology is almost two centuries old. If the Chinese couldn't mass produce this item at this price and still make a fair profit I would be very surprised.

First impressions (WOW!) a phenomenal product, in all respects. It has a very solid feel, fit and finish.A bargain and perfect for modeling a few concepts from scratch. My principle concern is low level fan noise, detracting from musical experience... it takes you out of the moment. We will see. *Not faulting DIY hz, more in that possible complexity could prove "conventional" heatsinks. I chose and "all aluminum" water system, heat block and heat exchange, to minimize reactive nature of (all parts in the) system.As a high power (audio/musical) A/B amplifier, heat dissipation, adequate heat sinking is required and/or could prove a penalty, in size, end product layout... falls around power transformer and heatsink. My thinking, thus the proof of concept supporting my personal designs... I can have "enough" dissipation for bias and maximum drive, for power listening (think 350-500wpc @8ohm) and have "enough" for the musical peaks. A robust 10 x 12 x 1.25 heatsink gets really hot, not dangerous... a problem with large heatsinks is uneven cooling / dissipation in the output stage possibly lending to low level non-linearities. typically the bottom portions of the heatsink are (convectively) cooler than the top. Place one (mono) amp nearer to an AC vent, a sun filled window or drafty room/basement, like mine ... it is common up to 10 degrees difference, channel to channel relative to placement, with large heatsinks, doin their job...I am excite to think WAY outside of the box, will update as project evolves, likely building one cooling chassis / tower for 2 mono amps, with several more garden hoses in the back ground, and not as a figure of speech.

Works really great, provided what I needed for my experiment.

I loved it! Thermodynamics in action.

Works perfect for my use. Well made, no leaks.

So far, I just don't know. Fan seems fine, spins freely by hand. Radiator is good, construction seems good and nice welds for the nipples for incoming and outgoing water flow.. Back to the fan, the fan does not power up using the red/black leads. It has continuity, just don't know. I will write some code to a microcontroller to see if that makes it hum. More to come, I'll update in a couple of weeks or so.

Good to go

I have been using this radiator in my PC for a little over a month now. Works great with no issues.I purchased this radiator to replace a busted leaking one on my hybrid GPU. With the new radiator, hoses and coolant, my GPU now works great. Runs nice and cool. No leaks. The quality was better than I expected for the price. Fit and finish are great. The hoses, clamps and screws are nice. My 120mm fan went right on and the provided screws went in easy.I am overall completely happy with my purchase.*The hoses are actually crystal clear, but they do react with uv or black lights.
