The impact of adding a secondary 240mm Radiator

post #1 of 5
Thread Starter 
Hi All,

My previous thread was a question, with the help from the overclock.net community I decided what route I'd like to take.

The Problem

So the problem I had is I have an Intel Core I5 4670K that is overclocked to 4.4GHz which is great, but I also have the ability to get a nice overclock on my R9 290 as well but I cannot run the graphics overclock because my current watercooling setup cannot remove the heat well enough and causes a system freeze after a while. After some opinions thrown I decided to purchase a second 240mm radiator (EK-Coolstream RAD XTX 240 Dual) as well as some Corsair SP-120 Low noise High Static Pressure fans for the radiator, this above most methods should have the greatest reduce in temperature.

Before I go and add a secondary radiator I wanted to keep a log so I know what my temperatures where before and then re-run the tests and see what impact it made.

Stress Tests with one dual 240mm Radiator in push configuration

I5 4690K Overclocked @ 4489.28MHz Stress Test with IntelBurnTest

Update
After Cyro999's post I decided to add a very quick bench along with some information from HWInfo which shows all relevant (well most) data. The new stress test (HW264 modified by "Angelotti") is more appropriate for haswell stress tests and didn't nearly fry my CPU like the other one in this post.

HW264 "Angelotti version"

CPU-Z




HWMonitor - Massive 90 Degree Celsius Temp at max





Intel Burn Test - Maximum stress settings (Not recommended for Haswell stress tests)




Sapphire R9 290 Overclocked @ Core: 1170MHz Memory: 1500MHz Benchmarked using Unigine Valley

I was looking for the best stress tests for GPU but there seems to be a lot of debate about stress tests providing unrealistic scenarios, the test is to see the impact of adding another dual radiator to the rig so I'll use Valley to provide a baseline







I've logged GPUZ temperatures to a file while running Unigine Valley and here are the max temperatures:

GPU Core Start Temp: 50 Degree's Celsius
GPU Core Max Temp: 69 Degrees Celsius
VRM1 Start Temp: 46 Degree's Celsius
VRM1 Max Temp: 91 Degree's Celsius
VRM2 Start Temp:[/B: 43 Degree's Celsius
VRM2 Max Temp: 59 Degrees Celsius



Later I'll strip the rig, clean, re-thermal paste and install a secondary dual 240mm radiator and re-test

Have you delidded the cpu? I found with my 3570k, that going from my Hyper 212 evo to water cooling made little to no difference, the IHS being the 'bottleneck'

Should definitely see an improvement with the GPU tho, I'm running a 360 and 240 rad, with corsair SP fans at about 700rpm, and it sees 50~c at full load, while overclocked smile.gif

Hi,

Thanks for your reply smile.gif no I haven't delided the CPU yet, it's something that I may very well do in the near future though as I hear of great temperature reducements. At the moment I'm a complete N00b in the overclocking area, I purchased the rig and all the settings had already been applied, with one of the presents selected in MSI after burner it causes the temperature to rise (obviously tongue.gif) but means in a game it won't last very long until the heat from the GPU overheats the CPU which is why I've chosen to go straight ahead with a new rad rather than just fans or delidding.

And those temperatures are awesome! I hope I can achieve something similar, however you have another 120mm of radiator extra fan and a nice delidded CPU so I'm going against odds. I hope this does the trick anyway, my Parvum case couldn't take any more radiators after this mod so fingers crossed =]

Oh my cpu isn't delidded, I'm not brave enough to do that redface.gif

Overclocking is easy, especially on these modern processors, literally thousands of guides about it. Easiest way ofc is to just up the vcore and multiplier smile.gif

I am running a Xeon 1230v3(all cores 3.7Ghz) and an R9 290(1200/1450) with two 240mm rads and with valley after one hour i get 72°C CPU and 73°C GPU.
Fans are Noiseblocker eloops running at 7V ~750rpm.

Temps differ quite alot depending on the exact setup you are running;)
Also did you wait for the watertemp to get equilibrium?
