Please post your toughts elsewher!
You're wrong even with the proof in front of you.

Test benching while it might eliminate the external variables, it doesn't represent a real case scenario.
You can have cooler 1, with X capacity heatsink and a slow fan, and cooler 2 with 0.9X capacity heatsink with a fast fan.

Cooler 2 will be better on the test bench, but cooler 1, might be equal or better in a well set up case.

I'm sorry. You can say whatever you want, but I'm seeing all the time results and leads from my testing and others that drives me and reinforce the same conclusion.

Your post is only more proof you lack the knowledge needed to perform accurate testing.

How can you determine a cooler's performance with the many variables in a case built system not being accounted for?

Obviously cooler fan speeds / noise levels are variables measured when bench testing and used for comparing coolers at same fan speed or same noise elvel. Same as monitoring air temp into cooler for delta temp performance.

No, every coolers' performance when tested on a bench is based on air temp, same fan speed / noise level, but because bench testing eliminates many of the varialbes not taken into account (like air temp into cooler, fan noise level, etc.) that in almost all case built testing are not taken into account and are therefore inaccurate.

Every cooler I've tested on bench test station performs the same in a case built system. Testing bench simply eliminates variables like not being able to acutally monitor fan noise in case build because of other fan noise in such close proximity they cannot be isolated from cooler fan's noise.


Either you are simply trooling or you don't understand basics of cooler testing.
Again, please take your posting elsewhere so it doesn't clutter up this thread.

Won't doing that move the gpu air towards the cpu?
I can see how it can cause a drop for low gpu load, but for heavy gpu load won't it cause a rise in temps?
The system is not mine, so i won't remove the hdd case. However I have removed all unused hdd bays.

Would help if we know what air temp into cooler is when system is at 100% load. 2nd & 5th posts this thread show what I use.

You could also remove filters, grills, etc. and block all openings in intake fan mounting panels and see if temps go down. This will give you an idea about what better pressure rated / higher airflow fans will do.

I don't like using rear as intake. I much prefer airflow from front to back with maybe a bottom intake to GPU. Remove all PCIe back slot covers to increase rear vent area around GPU to improve front to back airflow in this area and thus lower temps.
What 2nd speed curve? I don't understand what you mean here.

I have read the thread and have ordered a thermometer. It will probably arrive next month.
Do you suggest i delay replacing the fans until i can have concrete data with the thermometer?

I don't know about the GPU but I think using the back fan as an intake it should minimize the affect? The rule of thumb I've seen, based off testing with the back fan as an exhaust, is mount the CPU heatsync vertical for open GPU's and horizontal for blower/watercooled GPU's.

Just an idea if you have the time to try out.

Yes, turning cooler to flow air up means it will be drawing from back of GPU and pulling air in off of GPU side away from motherboard so yes, warmer air from GPU into cooler. The more turns air has to make the more turbulence there is and the more warmer air mixes into cool airflow warming it up.
Your forth fan curve is basically what I was saying, but have fan speed curve from 30-40c @ 600rpm to 40-50c @ 800rpm, to 50-60c @ 1100rpm, 60-70c @ 1200rpm an 70 +c @ full speed.
Monitoring air temp into cooler and comparing that temp to room air entering case tells us how much higher air temp into component is so we can work on case airflow and get air temp into cooler 5c or less above room temp.

I just realized that i cannot install the cooler vertically because the rams are very tall.

Temps seem kinda high for that speed. My 3770K needs 1.315 for 4600, and those are the temps I saw with Linpack and less case flow then I have now, but I was using a TY143 so that could be why.. Maybe try spinning your cooler 180 and see if there is any change. Too much TIM insulates, not enough TIM is well.. not enough.. I just benched my X5690 at 4800mhz @ 1.6v with it last week, so its pretty decent, and I did it with the windows closed

I have a TY147A and TY147B in push/pull using TF8 for TIM.

Yeah, my normal fan curve is like that because i prefer it quiet. I was just testing different fan speeds to see how they affect the temps.

This overclock was done quickly just for testing purposes. I know it is inefficient now i'm back in stock.
In the past the cpu needed 1.33v for 4.6GHz but now it needs more and i don't want to go beyond 1.35v. I will probably settle at whatever frequency i can achieve below 1.3v.
As for the temps one core is always 10 degrees less that the others. A delid would help but since i won't go for extreme overclocking, i won't bother with it.

Delidding didn't help on my 3570K with that "one core is always 10 degrees less than the others" problem. The same core's temperature was still off afterwards. I tried replacing the liquid metal another two times on the CPU, and the core kept being different.

I don't know what's going on there. I've seen people guess that it's simply the temperature sensor and not the actual core temperature. That one particular sensor is measuring differently than the ones from the other cores.
