A few days ago I spoke here in Skooter Blog on the RMA a liquid Cooler CPU Hydro Series ™ H80i Corsair. In it I mentioned that, in 2015, I assembled a PC to use in my work, with a Intel i7-4790k, that principle would use only the stock cooler.
But, the i7-4790k was very touchy, even in the not-too-heavy tasks. So I decided to purchase the Liquid CPU cooler Hydro Series ™ H80i, which lowered the temperatures, leaving them in acceptable levels even with my heavier software. But, in tests as Intel Burn Test and Prime 95, the processor still arrived at 100ºc and powered up the throttling.
Despite the problem, I used the PC anyway for a year and a half, whereas with day to day tasks he hasn't warmed up to the limits. But on one occasion the processor starts knocking in 100° C even in idle. Apparently there was some problem with the cooler liquid CPU Hydro Series ™ H80i, because on these occasions, even with the hot block, the radiator was cold.
So I decided to ask the RMA Cooler liquid CPU Hydro Series ™ H80i, having 5 year warranty, and I decided to also ask the RMA Intel i7-4790k, having 3 year warranty, and we definitely had some problem.
Both RMAs simultaneously I would be with the PC stopped only once. Furthermore, I had already scheduled a trip to September, in that would not use the PC anyway. Surprisingly the Corsair was faster in the RMA, contrary to previous experience, as I said in another article.
As for Intel, on the site of your “Warranty Center” are the numbers and ATPO FPO orders to verify that the product is under warranty. They say that these are the processor package. Removed so the processor, I cleaned the thermal paste, only to find out that, no caso do Intel i7-4790k, an ATPO number is encoded in something like a QR Code.
Now I found out that there are Android applications to read this ATPO number from a picture that needs to be taken with a macro lens. But at the time the only information I found was that the number could only be read with some special equipment that I had not.
In conversation with Intel at the chat site, asked to install software and run tests, which made me extremely mad because I had just remove the processor by auditors of confusing information that they pass, and I wasn't willing to ride it again, spend more thermal paste, just to run a diagnostic program to confirm (or not) the defect already known. Ended up releasing me from test, just asked to email processor box photos, processor and invoice. The RMA was authorised on the same day, 23/08/2016. Asked to send the processor to an address in Cajamar – SP. The freight was for my account. The posting was made on the day 25/08 and delivery was made the next day.
As after 3 working days still no demonstration of Intel, I got in touch and I was informed that “Officially your processdor was received at the depot last, must be sent today or tomorrow for you.”. And indeed, not give 01/09/2016 I was with the new processor in hands, received via Mail. Check out the photos:
The processor came in retail box, with the stock cooler (now I'm left with two and without using any), only with a big sticker covering half of the box.
At the time I was already with the new Cooler liquid CPU Hydro Series ™ GT H80i, the RMA Corsair, just waiting for the processor comes to be installed. Then did the installation of both as already reported in article about the RMA Corsair.
The new dual Intel i7-4790k + Cooler liquid CPU Hydro Series ™ GT H80i can maintain cold temperatures even when performing my most heavy tasks. Even in the most extreme tests with the Intel Burn Test and Prime 95, the processor cores don't spend a lot of 90° C, measured with the software Realtemp. With little processing it is around 40° C, within the expected.
I have been using the new Intel i7-4790k a month and a half. At least for now I can say that it is approved and presented no problems.
Let also a positive evaluation for Intel, that provided a good experience of RMA, just wasn't perfect because of the confusion with the FPO numbers and ATPO, and also for letting the shipping shipping the defective product for my business, In addition to not inform virtually nothing about the progress of the warranty process. But as plus point the whole process was completed in less than a week.
