Need assistance with water cooling?
Need assistance with water cooling?
Hi once more, everyone,
I had warned you all that I would return.
😉
Intro
I’m still searching for a superior cooling solution for my CPU, which is the i5-6400 OC to [email protected]. At the voltages I can apply with my current cooler—my Hyper 212 EVO—I manage only to reach this speed and sometimes a bit more, but it remains the most stable option. I’ve read through it, not entirely, but still working on them. The water cooling threads are very helpful, and I’d like to thank all the creators behind them.
To the real issue:
I’m seeking either a custom water cooling system that can handle both my CPU and GPU in one loop with minimal changes to my case. Ideally, I’d like to pass the case on to a family member once I have everything needed. I plan to upgrade to a full tower or a test bench style case. At first, I thought about an AIO, but it seems that many air coolers could improve performance over cheaper models without the risk of leaks.
😛
I’m considering options like the NZXT Kraken X61, Thermaltake Water 3.0 Ultimate, or Ekwb Predator 360. I know most of these water coolers won’t fit my case, but I’m open to routing the tubes outside the case and placing them on the wall behind the PC. However, after reading more about water cooling, I’m leaning toward a custom loop as it might better suit my needs. Right now, I can’t overclock the GPU because the cooler gets too noisy at those temperatures, and I’m limited in how much I can push the CPU since the cooler master would be too hot for the Hyper 212 EVO.
My budget is under 500 CAD (for now). If I can’t afford it, I can postpone or build it later. If it’s possible, I’d prefer the best quality components while keeping noise levels manageable—just not too high compared to the current setup with the 6 deepcool TF120 fans at full speed and the ACX 2.0 fans running at 80%.
Question:
1) What components would you suggest for cooling the CPU alone at 4.8Ghz?
2) What parts would work well for cooling the CPU and GPU together in one loop?
3) What would be best for cooling the CPU and GPU separately in two loops?
If I can manage to get all the necessary parts in black and red, I’d be very satisfied. But if that’s not feasible within my budget, I understand.
As for the questions above, if I can only afford a custom CPU loop initially, I’m fine with that. If not, would it make sense to consider an AIO for the CPU, knowing I’ll eventually switch to a custom solution?
I used an Excel spreadsheet to estimate the radiator area needed, but I couldn’t find the stock Vcore or TDP of the pump since I’m not familiar enough with current pump trends.
Thanks again for your support—it’s greatly appreciated. Below is the list of components currently in my build:
- Intel i5-6400
- GSKILL Ripjaws 16GB DDR4 2400MHZ
- GTX 970 SC ACX 2.0
- EVGA 750W Supernova
- Gigabyte Z170 DH3P
- Seagate Barracuda 2TB 7200 RPM HDD
- ADATA Premier 240GB 6GB/s SSD
- 5 Deepcool TF120 Red’s
- CoolerMaster Hyper 212 EVO
- Corsair Spec 01 Case
- Some random CD drive for program installation and ripping old CDs to WAV
EDIT: I’d also consider a large air cooler like the Noctua models, but with my current RAM and motherboard, I’m unsure if there’s enough space. If anyone has experience fitting Noctua into my Corsair Spec 01 case, that would be ideal—just as long as it keeps the CPU cool enough.
The EKWB Predator line is a reliable cooler for those entering the watercooling world. Other options exist for similar budgets in custom loops, but focusing on the Predators ensures high-quality components. I'm currently updating the v1.0 to v1.1. The 240 model handles a 10C delta efficiently, even with loads just over 300 watts. EK also offers plug-and-play GPU blocks that are ready to use, though you can select any GPU block and connect it using the available fittings and tubing.
The EKWB Predator line stands out as a reliable and effective cooler for those entering the watercooling world. Alternative builds might offer better performance at a similar cost in a custom loop, but given the Predators' design focus, it remains a solid choice. I'm currently updating the v1.0 to v1.1. The 240 model handles a 10C delta efficiently, even with loads exceeding 300 watts. EK also provides plug-and-play GPU blocks that are ready to install, though you can select any GPU block and connect it using your preferred fittings and tubing.
For CPU+GPU setups, I lean toward a Laing pump, either a DDC (with four to five main versions) or a D5 (commonly the 12v Vario). You can install a reservoir or top for either model, or run it separately—remember to keep the reservoir level higher than the pump inlet.
A full-cover GPU block is recommended. While you can opt for a universal solution, ensure you account for RAM, VRMs, and MOSFETs on the card to maintain proper cooling. The decision hinges on your budget and component preferences. For instance, I used an mITX build in a compact case, so I chose an EK pump and reservoir combo despite limited space. My CPU block is an older D-tek v2 that still performs well, paired with a 1155 conversion bracket. My GPU is a GTX 770 Acetal/Nickel EK full-cover block with a backplate (sourced from Ebay). I opted for Phobya fittings over Bitspower, though they function adequately.
The key takeaway is that custom loops offer numerous options, which can be both rewarding and challenging for new builders. Just keep in mind—most watercooling parts are compatible with a wide range of components due to the use of G1/4 fittings and standard tubing sizes like 3/8"ID or 1/2"ID (including metric equivalents).
The cost breakdown is roughly 500 CAD (~380 USD), depending on your choice. A full-cover GPU block typically costs around $110 USD (145 CAD) or more, unless you find a good deal. Pairing this with an EK XLC Predator 240 at $200 USD (263 CAD) pushes the total budget higher. While it may function, performance will vary based on CPU load and desired delta.
During testing, I found that running an i7 and a 970 processor on the cooler alone could maintain a 10C delta, though results depend on your specific setup. If you can locate your stock VCore for your i5 to fine-tune the CPU TDP, you might be able to estimate performance more accurately. The Predator also features quiet fans that operate efficiently even at high speeds. Securing an XLC 360 would add extra cooling capacity, but availability depends on space constraints.

If you’re considering the XLC 240, I suggest pairing it with a stock vcore for your i5 to calculate TDP accurately. The Predator also features quiet fans, especially at full speed. Securing an XLC 360 would add extra cooling capacity, but availability depends on finding a compatible case.
Thanks for the detailed advice. Your suggestions are helpful—I’ll follow up on the Vcore and spreadsheet details soon.
At the beginning, you mentioned custom loops could be built for similar costs that outperform. I’m planning to invest in a full-cover block since I can’t afford a replacement GPU. After this reply, I’ll look into the stock vcore and ask how you determine the pump’s TDP for systems matching the EKWB Predator or its current model. I’ve also read about needing sufficient airflow above voltage regulators on the motherboard—will the existing case fans (one at the back, two fronts) suffice?
As for the 360, getting it should be manageable once I locate a suitable case. I’ll likely measure available options and decide based on fit. If I can’t find a custom loop, I’ll settle for the Predator now and keep the noisy card in mind.
Thanks for all your support—I’ll await your response on Vcore and spreadsheet specifics!
Most pumps operate in the range of 12 to 30 watts. Adding or omitting just a few watts won’t significantly affect performance. It’s unclear why the EK Predator isn’t a suitable choice—would you like more information? For voltage regulators and fans, it depends; likely not unless you’re achieving strong airflow directly over them. If you’re overclocking without a CPU fan, airflow through these parts is usually restricted. It’s never wise to assume standard case fans are sufficient—always check carefully.
You can easily boost your 65w TDP CPU to 4.8ghz without needing air cooling alone!
I’m targeting the model linked below as a cooler alternative for my peltiers, and I’m confident it will manage an overclocked i5-6400. It’s a 150w Intel heat pipe air cooler.

Unless you plan to push beyond 4.8ghz in the future, the cost of water cooling isn’t necessary.
Regarding the EK Predator 240, I’m happy with its build quality and it’s easily handling my wife’s 2700k CPU overclock up to 4.5ghz.
The only thing that bothers me is the actual core thickness—it feels a bit thin compared to what I expect. It’s a letdown, but not a total loss since 4.5ghz is still impressive.
There’s roughly a 3/8th inch gap between the radiator frame and the core fins on each side, which is great for screw access, though it doesn’t provide much thickness for the core itself (about 20mm).
Personally, I don’t think it’s worth spending $200, but it’s well-made!
Given how heat pipe air coolers have failed over time, I opted for the EK Predator this time and won’t buy another one.
My two dollars!
P.S.: Not all radiators are alike, and TDP estimates today are based on older data. I hope future overclockers will see better radiator designs with clear wattage ratings in their specs.
Different radiator sizes can behave very differently because of core design, tubing patterns, fin density, etc.
So if we assume a 360 rad can handle a lot of power, it doesn’t mean every single one is the same—each needs individual testing for wattage.
It’s clear that a 360 rad with a 20mm core won’t match a 360 rad with a 40mm, 60mm, or 80mm core in cooling performance.
Therefore, before you commit to any water cooling gear, do thorough research—don’t rush into buying!
Core thickness is among the most significant factors, together with the radiator's FPI. The number of tubes in parallel runs is another consideration, though most 120mm and 140mm radiators typically feature similar counts per size. When creating the radiator estimation sheet, I included several models ranging from 30mm to larger ones up to 60mm thick. Only a handful reach 80mm or beyond, so the calculations consider not just power output but also average values derived from volume measurements. It's not an exact method, but it serves as a reasonable approximation for estimating cooling demands and load requirements.
Whoa rubix_1011, I’m not criticizing your estimation sheet, please don’t assume that. If I’m saying anything at all, it’s just that. What’s the point of radiator specs if they don’t mention the wattage load handling? Even the Alphacool NexXxos Monstas 86mm framed thickness model doesn’t list the load handling details—just other things you can think of, right? It’s a bit frustrating because the cooling performance should be roughly double that of a 40mm thick radiator. If wattage capacity was listed, it would definitely boost sales for some and hurt others. But if they had to rate the capability, it would remove a lot of guesswork, especially for overclockers after high stable overclocks.
Given how many premium heat pipe air coolers now focus on their power handling, it seems reasonable that the water cooling sector should also assess their radiator performance in terms of wattage capacity. They ought to be required to provide at least a load rating that includes specific fan specifications.
I wasn't trying to take your work for granted, but I aimed to explain the averaged and median values of the radiators using data from Martin and Skinnee. It would be great if there were a proper data sheet showing how much heat each radiator could handle at various flow speeds and fan settings. A basic chart would suffice as long as the information was collected and shown correctly. Radiators should be able to standardize their load ratings, just like air coolers do.
